New study: Harvard professor finds no racial bias in police shootings

Leave a comment

If there’s one thing that the secular left wants you to believe about the police, it’s that white police officers are constantly shooting innocent black people with no criminal records for “crimes” like wearing “baggy pants”. When I speak with secular leftists, especially women, this view is taken as being as true as the fact that the Earth orbits the Sun. But is it?

You might not know about this, but there is a pretty interesting black professor of Economics teaching at Harvard University. The Free Press has an article about him:

Roland Fryer, an economics professor at Harvard, is a superstar by any measure. At the age of 30, he became the youngest black person ever to receive tenure at the Harvard. The MacArthur Foundation declared him a genius in 2011. And in 2015 Fryer won the prestigious John Bates Clark Medal, given yearly to the most promising economist under 40.

[…]Abandoned at birth by his mother, Fryer clawed his way out of poverty to land a spot at the University of Texas, Arlington, earned his Ph.D. at Penn State, done postdoctoral research at the University of Chicago with the Nobel Laureate Gary Becker, and, finally, wound up at Harvard, where he eventually met his wife, a biologist, and became one of the university’s most celebrated professors.

OK, that’s very interesting. But now he’s authored a new study that has caused him to require armed security.

Here’s a report about it from the Daily Caller, based on a recent interview with Bari Weiss.

Harvard economics Professor Roland Fryer needed armed security with him to go out in public after he published a study finding no evidence of racial bias in officer-involved shootings, he said in an interview with The Free Press founder Bari Weiss.

Fryer, a top economist who became the youngest tenured black professor in Harvard’s history at just 30 years old, published a study in 2016 showing there was “no racial differences in officer involved-shootings.” After he published the study, “all hell broke loose,” Fryer told Weiss, noting people “lose their mind when they don’t like the result.”

“I lived under police protection for about 30 to 40 days,” he said during the interview. “I had a seven day old daughter at the time…I was going to the grocery store to get diapers with an armed guard.”

And here is his conclusion:

“On the most extreme use of force – officer involved shootings – we find no racial differences in either the raw data or when contextual factors are taken into account,” Fryer’s study found.

[…]He said he was “surprised” by the result because he expected to find evidence of bias.

[…]After the study was complete, Fryer said he hired eight additional freshmen to redo the study but came up with the same result.

Alexander Vilenkin: “All the evidence we have says that the universe had a beginning”

2 Comments

I’ve decided to explain why physicists believe that there was a creation event in this post. That is to say, I’ve decided to let famous cosmologist Alexander Vilenkin do it.

From Uncommon Descent.

Excerpt:

Did the cosmos have a beginning? The Big Bang theory seems to suggest it did, but in recent decades, cosmologists have concocted elaborate theories – for example, an eternally inflating universe or a cyclic universe – which claim to avoid the need for a beginning of the cosmos. Now it appears that the universe really had a beginning after all, even if it wasn’t necessarily the Big Bang.

At a meeting of scientists – titled “State of the Universe” – convened last week at Cambridge University to honor Stephen Hawking’s 70th birthday, cosmologist Alexander Vilenkin of Tufts University in Boston presented evidence that the universe is not eternal after all, leaving scientists at a loss to explain how the cosmos got started without a supernatural creator. The meeting was reported in New Scientist magazine (Why physicists can’t avoid a creation event, 11 January 2012).

[…]In his presentation, Professor Vilenkin discussed three theories which claim to avoid the need for a beginning of the cosmos.

The three theories are chaotic inflationary model, the oscillating model and quantum gravity model. Regular readers will know that those have all been addressed in William Lane Craig’s peer-reviewed paper that evaluates alternatives to the standard Big Bang cosmology.

But let’s see what Vilenkin said.

More:

One popular theory is eternal inflation. Most readers will be familiar with the theory of inflation, which says that the universe increased in volume by a factor of at least 10^78 in its very early stages (from 10^−36 seconds after the Big Bang to sometime between 10^−33 and 10^−32 seconds), before settling into the slower rate of expansion that we see today. The theory of eternal inflation goes further, and holds that the universe is constantly giving birth to smaller “bubble” universes within an ever-expanding multiverse. Each bubble universe undergoes its own initial period of inflation. In some versions of the theory, the bubbles go both backwards and forwards in time, allowing the possibility of an infinite past. Trouble is, the value of one particular cosmic parameter rules out that possibility:

But in 2003, a team including Vilenkin and Guth considered what eternal inflation would mean for the Hubble constant, which describes mathematically the expansion of the universe. They found that the equations didn’t work (Physical Review Letters, DOI: 10.1103/physrevlett.90.151301). “You can’t construct a space-time with this property,” says Vilenkin. It turns out that the constant has a lower limit that prevents inflation in both time directions. “It can’t possibly be eternal in the past,” says Vilenkin. “There must be some kind of boundary.”

A second option explored by Vilenkin was that of a cyclic universe, where the universe goes through an infinite series of big bangs and crunches, with no specific beginning. It was even claimed that a cyclic universe could explain the low observed value of the cosmological constant. But as Vilenkin found, there’s a problem if you look at the disorder in the universe:

Disorder increases with time. So following each cycle, the universe must get more and more disordered. But if there has already been an infinite number of cycles, the universe we inhabit now should be in a state of maximum disorder. Such a universe would be uniformly lukewarm and featureless, and definitely lacking such complicated beings as stars, planets and physicists – nothing like the one we see around us.

One way around that is to propose that the universe just gets bigger with every cycle. Then the amount of disorder per volume doesn’t increase, so needn’t reach the maximum. But Vilenkin found that this scenario falls prey to the same mathematical argument as eternal inflation: if your universe keeps getting bigger, it must have started somewhere.

However, Vilenkin’s options were not exhausted yet. There was another possibility: that the universe had sprung from an eternal cosmic egg:

Vilenkin’s final strike is an attack on a third, lesser-known proposal that the cosmos existed eternally in a static state called the cosmic egg. This finally “cracked” to create the big bang, leading to the expanding universe we see today. Late last year Vilenkin and graduate student Audrey Mithani showed that the egg could not have existed forever after all, as quantum instabilities would force it to collapse after a finite amount of time (arxiv.org/abs/1110.4096). If it cracked instead, leading to the big bang, then this must have happened before it collapsed – and therefore also after a finite amount of time.

“This is also not a good candidate for a beginningless universe,” Vilenkin concludes.

So at the end of the day, what is Vilenkin’s verdict?

“All the evidence we have says that the universe had a beginning.”

This is consistent with the Borde-Guth-Vilenkin Theorem, which I blogged about before, and which William Lane Craig leveraged to his advantage in his debate with Peter Millican.

The Borde-Guth-Vilenkin (BGV) proof shows that every universe that expands must have a space-time boundary in the past. That means that no expanding universe, no matter what the model, can be eternal into the past. No one denies the expansion of space in our universe, and so we are left with a cosmic beginning. Even speculative alternative cosmologies do not escape the need for a beginning.

Conclusion

If the universe came into being out of nothing, which seems to be the case from science, then the universe has a cause. Things do not pop into being, uncaused, out of nothing. The cause of the universe must be transcendent and supernatural. It must be uncaused, because there cannot be an infinite regress of causes. It must be eternal, because it created time. It must be non-physical, because it created space. There are only two possibilities for such a cause. It could be an abstract object or an agent. Abstract objects cannot cause effects. Therefore, the cause is an agent.

Now, let’s have a discussion about this science in our churches, and see if we can’t train Christians to engage with non-Christians about the evidence so that everyone accepts what science tells us about the origin of the universe.

William Lane Craig explains how Christianity answers evil and suffering

3 Comments

A lot of people in the West complain too much about any little suffering they have to experience. But sometimes, when a very harsh suffering is felt by someone who has tried to follow Jesus, an explanation is necessary. I found something very good on the Reasonable Faith web site, written by Dr. William Lane Craig.

He makes the following points:

  1. We are not in a good position to assess the probability of whether God has morally sufficient reasons for the evils that occur.
  2. The Christian faith entails doctrines that increase the probability of the co-existence of God and evil.
  3. Relative to the full scope of the evidence, God’s existence is probable.

I’ve written before about point #1, in which Dr. Craig’s describes the limitations of human knowledge that make it hard for us to know for certain that a specific evil or suffering does not have a good reason for God to allow it. And I’ve written about #3, in which Dr. Craig makes some arguments for God’s existence. But #2 might be new to some of you, so let’s look at that.

He makes four sub points in section 2 about Christian doctrines that make the existence of evil and suffering more reasonable.

  • 2. a)The chief purpose of life is not happiness, but the knowledge of God.
  • 2. b) Mankind is in a state of rebellion against God and His purpose.
  • 2. c) The knowledge of God spills over into eternal life. 
  • 2. d) The knowledge of God is an incommensurable good.

My favorite one is 2. a), so let’s look at that one. He says:

2. a. The chief purpose of life is not happiness, but the knowledge of God. One reason that the problem of evil seems so puzzling is that we tend to think that if God exists, then His goal for human life is happiness in this world. God’s role is to provide comfortable environment for His human pets. But on the Christian view this is false. We are not God’s pets, and man’s end is not happiness in this world, but the knowledge of God, which will ultimately bring true and everlasting human fulfillment. Many evils occur in life which maybe utterly pointless with respect to the goal of producing human happiness in this world, but they may not be unjustified with respect to producing the knowledge of God. Innocent human suffering provides an occasion for deeper dependency and trust in God, either on the part of the sufferer or those around him. Of course, whether God’s purpose is achieved through our suffering will depend on our response. Do we respond with anger and bitterness toward God, or do we turn to Him in faith for strength to endure?

You know, I always get confused when I see Christians trying to follow the script of the world and trying to make themselves feel good with consumer purchases, travel, fun experiences, showing off to others, etc. When I read the story of Jesus, it’s pretty clear that the normal Christian life, if the person is following Jesus at all, is about suffering the disapproval and opposition of non-Christians while you remain faithful and obedient to God. Today, there’s probably no better example of this than defending unborn children from adult selfishness. Although, defending born children from selfish adults who seek to deprive children of their biological mother and father is pretty bad, too. Nobody is going to like you for restricting their fun (i.e. – abortion, divorce, adultery, homosexuality, etc.), but being willing to take the heat from non-Christians for the sake of promoting what God thinks is right is true Christianity. It’s what Jesus would do.

Anyway, the one I’ve been thinking about more lately is 2. d), where Dr. Craig writes this:

2. d) The knowledge of God is an incommensurable good. To know God, the source of infinite goodness and love, is an incomparable good, the fulfillment of human existence. The sufferings of this life cannot even be compared to it. Thus, the person who knows God, no matter what he suffers, no matter how awful his pain, can still say, “God is good to me,” simply by virtue of the fact that he knows God, an incomparable good.

I sometimes feel pretty stressed out about Americans who were born in conservative states, raised by two married Christian parents, attended Christian schools and youth groups, and then abandoned their faith for atheism as soon as they hit college. It really bothers me how people who had all these advantages turned their backs on God, and they’re ungrateful for all their blessings. They show no curiosity about God – they don’t want to know him. But when you read the gospels to see what Jesus has to say about these sorts of people, it’s very comforting. He really sees the problem, and he is on the side of the little guy who has to struggle to be faithful and obedient to God. The Bible has nothing to say to people who are able to feel happy and successful apart from God. It speaks to people who are struggling to follow God. Even when things are difficult, Jesus speaks to the problem of being an alien and a stranger in a world that turns its back on him.
