New study: smoking marijuana/cannabis permanently lowers IQ

From the UK Telegraph.

Excerpt:

Teenagers who regularly smoke cannabis are putting themselves at risk of permanently damaging their intelligence, according to a landmark study.

Researchers found persistent users of the drug, who started smoking it at school, had lower IQ scores as adults.

They were also significantly more likely to have attention and memory problems in later life, than their peers who abstained.

Furthermore, those who started as teenagers and used it heavily, but quit as adults, did not regain their full mental powers, found academics at King’s College London and Duke University in the US.

They looked at data from over 1,000 people from Dunedin in New Zealand, who have been followed through their lives since being born in 1972 or 1973.

Participants were asked about cannabis usage when they were 18, 21, 26, 32 and 38. Their IQ was tested at 13 and 38. In addition, each nominated a close friend or family member, who was asked about attention and memory problems.

About one in 20 admitted to starting cannabis use before the age of 18, while a further one in 10 took up the habit in the early or mid 20s.

Professor Terrie Moffitt, of KCL’s Institute of Psychiatry, who contributed to the study, published in the journal Proceedings of the National Academy of Sciences, said “persistent users” who started as teenagers suffered a drop of eight IQ points at the age of 38, compared to when they were 13.

The truth is that permissive drug policies have been tried and they have failed.

Amsterdam authorities say they are to halve the number of brothels and marijuana shops in the city’s “red light” district and surrounding area

The city announced plans to clean up the area a year ago and since then 109 sex “windows”, from which prostitutes attract customers, have been closed. The new measures aim to reduce the number of windows to 243 from 482 last year, a city spokesman said.

Amsterdam also wants to close half of the 76 cannabis shops in the city centre.

“Money laundering, extortion and human trafficking are things you do not see on the surface but they are hurting people and the city. We want to fight this,” deputy mayor of Amsterdam Lodewijk Asscher told Reuters.

“We can still have sex and drugs but in a way that shows the city is in control.”

Prostitution was legalised in the Netherlands in 2000 and its soft drug policy, one of the most liberal in Europe, allows the sale of marijuana and possession of less than 5 grams (0.18 oz).

But Amsterdam’s toughening line is part of a wider trend in Holland.

Two Dutch cities near the Belgian border want to close all their cannabis shops to combat drug tourism and crime.

The 800-year-old red light district needs to diversify and showcase the city’s history, Mr Asscher said.

“This is a nice, old part of town. We can attract different groups of tourists. You should be able to have a beer at the old church square, watch fashion, and visit Chinatown,” he added.

The Family Research Council explains how permissive drug policies don’t actually work as advertised anywhere they’ve been tried.

Excerpt:

Legalizers believe most black market and organized syndicate involvement in the drug business would die and that drug-induced crime would decrease with drug legalization. But these assertions are not supported by the facts. The United States experimented with legalization and it failed. From 1919 to 1922, government-sponsored clinics handed out free drugs to addicts in hopes of controlling their behavior. The effort failed. Society’s revulsion against drugs, combined with enforcement, successfully eradicated the menace at that time.[32]

California decriminalized marijuana in 1976, and, within the first six months, arrests for driving under the influence of drugs rose 46 percent for adults and 71.4 percent for juveniles.[33] Decriminalizing marijuana in Alaska and Oregon in the 1970s resulted in the doubling of use.[34] Patrick Murphy, a court-appointed lawyer for 31,000 abused and neglected children in Chicago, says that more than 80 percent of the cases of physical and sexual abuse of children now involve drugs. There is no evidence that legalizing drugs will reduce these crimes, and there is evidence that suggests it would worsen the problem.[35]

Legalization would decrease drug distribution crime because most of those activities would become lawful. But would legalization necessarily reduce other drug-related crime like robbery, rape, and assault? Presumably legalization would reduce the cost of drugs and thus addicts might commit fewer crimes to pay for their habits. But less expensive drugs might also feed their habit better, and more drugs means more side effects like paranoia, irritability and violence. Suggestions that crime can somehow be eliminated by redefining it are spurious. Free drugs or legalizing bad drugs would not make criminal addicts into productive citizens. Dr. Mitchell S. Rosenthal, expert on drugs and adolescents and president of Phoenix House, a resident treatment center in New York, said, “If you give somebody free drugs you don’t turn him into a responsible employee, husband, or father.”[36] The Justice Department reports that most inmates (77.4 percent male and 83.6 percent female) have a drug history and the majority were under the influence of drugs or alcohol at the time of their current offense. And a surprisingly large number of convicted felons admit their crime motive was to get money for drugs. For example, 12 percent of all violent offenses and 24.4 percent of all property offenses were drug-money motivated.[37]

[…]The extent to which individuals commit “drug-related crimes only” is overstated. Most incarcerated “drug”offenders violated other laws as well. Princeton University professor John Dilulio found that only 2 percent — i.e., 700 — of those in federal prisons were convicted of pure drug possession. They generally committed other and violent crimes to earn a sentence.[40]

However, 70 percent of current inmates were on illegal drugs when arrested and, if drugs become cheaper, violent crime could reasonably be expected to increase.[41]

How well did permissive drug laws work in other countries?

History provides evidence that legalization of drugs in foreign nations has not been successful. For example, opium was legalized in China earlier this century. That decision resulted in 90 million addicts and it took a half-century to repair the damage.[59]

Egypt allowed unrestricted trade of cocaine and heroin in the 1920s. An epidemic of addiction resulted. Even in Iran and Thailand, countries where drugs are readily available, the prevalence of addiction continues to soar.[60]

Modern-day Netherlands is often cited as a country which has successfully legalized drugs. Marijuana is sold over the counter and police seldom arrest cocaine and heroin users. But official tolerance has led to significant increases in addiction. Amsterdam’s officials blame the significant rise in crime on the liberal drug policy. The city’s 7,000 addicts are blamed for 80 percent of all property crime and Amsterdam’s rate of burglary is now twice that of Newark, New Jersey.[61] Drug problems have forced the city to increase the size of the police force and the city fathers are now rethinking the drug policy.[62]

Dr. K. F. Gunning, president of the Dutch National Committee on Drug Prevention, cites some revealing statistics about drug abuse and crime. Cannabis use among students increased 250 percent from 1984 to 1992. During the same period, shootings rose 40 percent, car thefts increased 62 percent, and hold-ups rose 69 percent.[63]

Sweden legalized doctor prescriptions of amphetamines in 1965. During the first year of legalization, the number of intravenous”speed” addicts rose 88.5 percent. A study of men arrested during the legalization period showed a high correlation between intravenous use and a variety of crimes.[64]

Dr. Nils Bejorot, director of the Swedish Carnegie Institute and professor of social medicine at the Karolinska Institute in Stockholm, believes the solution to the growing drug problem is consistent social and legal harassment of both users and dealers.[65]

Great Britain experimented with controlled distribution of heroin between 1959 and 1968. According to the British Medical Journal, the number of heroin addicts doubled every sixteen months and the increase in addicts was accompanied by an increase in criminal activity as well.[66] And British authorities found that heroin addicts have a very good chance of dying prematurely. On the crime front, Scotland Yard had to increase its narcotics squad 100 percent to combat the crime caused by the “legal” addicts.[67]

The Swiss opened a “legalized drug” area in Zurich seven years ago and local addicts were given drugs, clean needles, and emergency medical care. Unfortunately, the liberal policy backfired and the number of addicts surged to 3,500; violence surged, too. “Needle Park,” as it came to be known, was a place of open warfare among rival gangs, and even police faced gunfire. Their cars were attacked and overturned. In February 1995, officials ended the experiment, conceding that it had evolved into a grotesque spectacle.[68]

Why does legalizing drugs increase crime? Because drugs are addictive and they cost money to obtain. Addiction reduces the ability to hold down a job, which is a legal way of getting money. Therefore, addicts will resort to crime in order to get the money to buy their drugs, since their addiction impairs their ability to hold down a job.

New study: time spent with father increases teen’s self-esteem

Surprisingly, this story is from the radically left-wing, anti-marriage CNN.

Excerpt:

The time teens spend specifically with their dads may have critical benefits, the study from Pennsylvania State University found. The more time spent alone with their fathers, the higher their self-esteem; the more time with their dads in a group setting, the better their social skills.

“The stereotype that teenagers spend all their time holed up in their rooms or hanging out with friends is, indeed, just a stereotype,” said Susan McHale, director of the Social Science Research Institute at Penn State. “Our research shows that, well into the adolescent years, teens continue to spend time with their parents and that this shared time, especially shared time with fathers, has important implications for adolescents’ psychological and social adjustment.”

Researchers studied families with at least two children over a period of seven years.

[…]The study, published in the journal Child Development, found that kids spend less and less time with their parents in group settings as they go through their preteen and teenage years. But one-on-one time increases up until about age 12 and then stays relatively flat before starting to decline a bit around age 15, says Crouter.

Parents spend roughly seven to eight hours a week in group settings with their kids ages 8 to 15, the study found. Mothers get in about an hour and 15 minutes alone with their firstborn kids and more than an hour and a half with second-born kids each week. Dads get in just over an hour of one-on-one time with first- and second-born kids each week.

Numerous other studies have found benefits for kids who spend more time with their families, such as fewer delinquent behaviors and less likelihood to give in to peer pressure, the study notes.

In this study, the findings about fathers proved to be very interesting, Crouter said.

While increased time with Dad showed key benefits for self-esteem and “social competence,” time with Mom did not show the same correlations.

Surprisingly, people today seem to be very much in favor of relaxing all rules around sex and marriage, so that it becomes less and less likely that children will grow up with a father. Make no mistake – the more people push for “non-judgementalism” about sexual boundaries and marital roles, the more children will grow up fatherless. If we really cared about children, we would encourage people to do what works: chastity and fidelity.

William Lane Craig debates Victor Stenger: Does God Exist?

Here are the details of the debate that I got from Cloud of Witnesses:

The OSU [Oregon State University] Socratic Club will sponsor a public dialogue entitled, “Two Philosophers Debate the Existence of God,” on Monday, March 1, at 7 p.m. in the LaSells Stewart Center on the OSU campus.  William Lane Craig will argue for the Christian view that a personal God exists and Victor J. Stenger the atheist position that there is no God.

In this debate, Victor Stenger does affirm his belief that the universe could be eternal in his second rebuttal (1:02:30), thus denying the standard Big Bang cosmology. He also denies the law of conservation of energy and asserts that something can come from nothing in his concluding speech (1:33:50). He also caused the audience to start laughing when he said that Jesus was not moral and supported slavery. There is almost no snark in this summary. Instead, I quoted Dr. Stenger verbatim in many places. I still think that it is very entertaining even without the snarky paraphrasing.

The debate includes 30 minutes of Q&A with the students.

Here is the MP3 file for the audio.

Here’s the video of the debate:

Dr. Craig’s opening speech:

  • The ontological argument
  • The contingency argument
  • The cosmological argument
  • The moral argument
  • The resurrection of Jesus (3-fact version)
  • Religious experience

Dr. Stenger’s opening speech:

  • There is no scientific evidence for God’s existence in the textbooks
  • There is no scientific evidence for God acting in the universe
  • God doesn’t talk to people and tell them things they couldn’t possibly know
  • The Bible says that the Earth is flat, etc.
  • There is no scientific evidence that God answers prayers
  • God doesn’t exist because people who believe in him are ignorant
  • Human life is not optimally designed and appears to be the result of a blind, ad hoc evolutionary process
  • The beginning of the universe is not ordered (low entropy) but random and chaotic
  • It’s theoretically possible that quantum tunneling explains the origin of the universe
  • The laws of physics are not objectively real, they are “our inventions”
  • Regarding the beginning of the universe, the explanation is that something came from nothing*
  • Nothing* isn’t really nothing, it is “the total chaos that we project existed just before the big bang”
  • If something has no structure, then “it is as much nothing as nothing can be”
  • Consciousness is explainable solely on the basis of material processes
  • There are well-informed, rational non-believers in the world and God would not allow that

Dr. Craig’s first rebuttal:

Stenger’s argument that there is no objective evidence for God’s existence:

  • First, it is not required that God rely only on objective evidence in order to draw people to himself (Alvin Plantinga)
  • Second, God is not required to provide evidence to everyone, only to the people who he knows would respond to him
  • Third, Craig gave lots of objective evidence, from science, history and philosophy
  • Stenger asks for certain evidence (answered prayers, prophecy, etc.), but Craig presented the evidence we have

Stenger’s argument that the balance of energy is zero so “nothing” exists:

  • if you have the same amount of assets and liabilities, it doesn’t mean that nothing exists – your assets and liabilities exist
  • Christopher Isham says that there needs to be a cause to create the positive and negative energy even if they balance
  • the quantum gravity model contradicts observations
  • the vacuum is not the same as nothing, it contains energy and matter
  • the BVG theorem proves that any universe that is expanding must have a beginning

Stenger’s argument that mental operations can be reduced to physical operations:

  • mental properties are not reducible to physical properties
  • epiphenomenalism: is incompatible with self-identity over time
  • epiphenomenalism: is incompatible with thoughts about other things
  • epiphenomenalism: is incompatible with free will
  • substance dualism (mind/body dualism) is a better explanation for our mental experience
  • God is a soul without a body
Dr. Stenger’s first rebuttal:

Craig’s cosmological argument:

  • Craig’s premise is “everything has a cause”, but quantum mechanics has causeless events
  • There are speculative theories about how something could have come into being uncaused out of nothing
  • “I don’t know of a single working cosmologist today who believes there was a singularity prior to the Big Bang”
  • “If there wasn’t a singularity then there’s no basis for arguing that time began at that point”
  • “There’s no reason from cosmology that we know of that the universe can’t be eternal”
  • “When I talk about an eternal universe, I mean a universe that has no beginning or end”
  • The Hartle-Hawking model doesn’t have a beginning
  • “There was no violation of energy conservation by having a universe coming from nothing”
  • “The universe could have come from a previous universe for example or even just from a region of chaos”
  • The paper by Vilenkin is counteracted by other papers (he doesn’t specify which ones)

Craig’s moral argument:

  • Dr. Craig is arguing from ignorance
  • But morality can be decided by humanity just like governments pass laws, and that’s objective
  • Dr. Craig has too little respect for the human intellect
  • I don’t need to tell me that slavery is wrong
  • The Bible supports slavery
  • Atheists can behave as good as theists
  • Morality just evolved naturally as an aid to survival

Craig’s resurrection argument:

  • No Roman historians wrote about the execution of Jesus but none of them did
  • The empty tomb is doubtful because it is only mentioned in the gospels, not by Paul
  • John Dominic Crossan says there was no empty tomb
  • Christianity only survived because the Roman empire thought that they were useful

Dr. Craig’s second rebuttal:

Craig’s cosmological argument:

  • There is no reason to prefer an indeterministic interpretation of quantum mechanics
  • Dr. Stenger himself wrote that deterministic interpretations of quantum mechanics are possible
  • The vacuum in quantum mechanics is not nothing
  • The quantum vacuum he proposes cannot be eternal
  • The cosmological argument does not require a singularity
  • The Hartle-Hawking model is from 1983
  • Hawking says that there is a beginning of space and time after that model
  • The Hartle-Hawking model does still have a beginning of time – the model is not eternal
  • The BVG theorem that requires a beginning for expanding universes is widely accepted among cosmologists

Craig’s moral argument:

  • Stenger redefined objective to mean that most people agree with it – but that’s not what objective means
  • Objective means right and wrong whether anyone accepts it or not
  • Richard Dawkins himself says that on atheism there is “no evil and no good” – why is he wrong?
  • Even Dr. Stenger says that morality is the same as passing laws – it’s arbitrary and varies by time and place
  • But on his view, right and wrong are the same as deciding which side of the road to drive on
  • But somethings really are right and some things are really wrong

Craig’s resurrection argument:

  • Josephus is a Roman historian and he wrote about Jesus, for example
  • There were four biographies of Jesus are the best sources for his life
  • The scholars that Stenger mentioned are on the radical fringe

Dr. Stenger’s second rebuttal:

Knowledge and the burden of proof:

  • Dr. Craig has to bear the burden of proof, not me – because his claim is more “extravagant”
  • “I don’t have to prove that a God was not necessary to create the universe”
  • “I don’t have to prove that a God did not design the universe and life”
  • “I don’t have to prove that the universe did not have a beginning”
  • “I don’t have to prove that God did not provide us with our moral sense”
  • There are a lot of books written about how morality evolved naturally
  • “I don’t have to prove that the events surrounding the supposed resurrection of Jesus did not take place”
  • Bart Ehrman says that the gospels are generally unreliable (Note: Ehrman accepts all 3 of Craig’s minimal facts)
  • Just because people are willing to die for a cause, does not make their leader God, e.g. – the Emperor of Japan

Aesthetic concerns about the universe:

  • I don’t like dark matter and I wouldn’t have made the universe with dark matter
  • I don’t like the doctrine of penal substitution
  • I don’t like the doctrine of original sin
  • I don’t like the heat death of the universe

Dr. Craig’s conclusion:

The case for atheism:

  • Dr. Stenger had two arguments and he has to support his premises
  • Dr. Craig addressed his two arguments and each premise and Dr. Stenger never came back on it

The contingency argument:

  • Dr. Stenger has dropped the refutation of this argument

The cosmological argument:

  • The theoretical vacuum he proposes cannot be eternal

The moral argument:

  • He asserts that things are wrong, but there is no grounding for that to be objective on atheism

The resurrection of Jesus:

  • There are surveys of scholars on the empty tomb and 75% of them agree with it
  • Bart Ehrman agrees with all 3 of the minimal facts that Dr. Craig presented
  • Ehrman’s objection to the resurrection is not historical: he’s an atheist – he thinks miracles are impossible

Religious experience:

  • No response from Dr. Stenger

Dr. Stenger’s conclusion

The cosmological argument:

  • “I argued that we have very good physical reasons to understand how something can come from nothing”
  • “There is a natural tendency in the universe… to go from.. simpler thing to the more complicated thing”
  • The transition from a vapor to a liquid to ice shows how something could come from nothing
  • “It cannot be proven that the universe had a beginning”

The moral argument:

  • Objective morality, which is independent of what people think, could be developed based on what people think
  • “Jesus himself was not a tremendously moral person… he had no particular regard for the poor… he certainly supported slavery… he was for the subjugation of women” (audience laughter)

The resurrection argument:

  • Bart Ehrman says that the majority of the gospels are unreliable

Religious experience:

  • I don’t see any evidence that there is anything more to religious experience than just stuff in their heads

God’s purpose of the world should be to make people feel happy:

  • God could have made people feel happier
  • God could have made people not die
  • God could could have made the universe smaller: it’s too big
  • God could have made it possible for humans to live anywhere “even in space”
