Frank Turek’s Criminally Bad C.R.I.M.E.S. Argument: Reason

Frank Turek’s Criminally Bad C.R.I.M.E.S. Argument: Reason August 5, 2013

This is a continuation of a critique of Frank Turek’s arguments in favor of Christianity made at a recent debate. See the beginning of the discussion here.

The R in CRIMES is Reason

Turek said, “If you’re an atheist, you can’t justify reason.” He says that Darwin knew this. Darwin said, “Would any one trust in the convictions of a monkey’s mind, if there are any convictions in such a mind?” If our minds are just the end result of a long series of evolutionary steps, why trust them?

First, who cares what Darwin said? If the subject is History of Science, that’s interesting. If it’s simply what evolution or physiology say today, we’re not bound by what Darwin says. No one consults Darwin’s writings to ensure that the latest findings don’t contradict the great man.

The fallible human brain

Second, I agree that our brains are quite fallible. Who would disagree? This passage from my book Future Hype (2006) summarizes some of our blind spots.

Ongoing risks with a track record (such as the number of deaths per year) are easy to compare with each other. Nevertheless, most people weigh risks poorly. The average American is much likelier to die in a car accident than a plane crash, much likelier to die from lightning than fireworks, and much likelier to die from influenza than anthrax. You’re less likely to win the jackpot in a major lottery than to die in an accident while driving to buy the ticket. The likeliest calamity that could happen to a traveler to another country is not terrorism or kidnapping, but a car accident. Tornadoes and hurricanes combined aren’t as deadly as heat waves; heroin and cocaine combined aren’t as deadly as alcohol. Risk experts say that nuclear power is quite safe and swimming is not, while most people feel the opposite. Money spent on disease research is only vaguely proportional to each disease’s impact. We worry about cell phones and brain cancer when we should be worried about cell phones and driving. The public’s ranking of fears doesn’t match up with the real risks, and a technology with the same death rate as a natural risk is perceived as more dangerous.

Here are more examples of the fallibility of our brains.

  • Our brains play tricks on us: consider placebos, psychosomatic illnesses, and phantom limb pain.
  • We can be fooled by optical and auditory illusions. Pareidolia is seeing patterns where none exist—a message in a song played backwards or the face of Mary in a grilled cheese sandwich, for example. Coincidences can seem meaningful even when random.
  • We confuse confidence with accuracy when we overestimate how reliable our memories are. Richard Wiseman’s awesome color-changing card trick shows that your skills at observation may not be as good as you might think.
  • We’re poor at weighing harm. We’re in the middle of Discovery Channel’s Shark Week, but based on how many people are actually killed, Cow Week would make more sense. That’s right—cows kill more people than sharks. Psychic numbing is a related problem. This is the observation, “One death is a tragedy; a million is a statistic.”
  • A popular misconception in South Korea is that electric fans in closed rooms can be deadly, but we Americans shouldn’t get too cocky. We have our own blind spots. In a 2013 poll of Americans, 21% say a UFO crashed in Roswell, 28% believe Saddam Hussein was involved in 9/11, 20% believe there is a link between childhood vaccines and autism, 7% think the moon landing was faked, 13% think Barack Obama is the anti-Christ, 14% say the CIA created the crack epidemic, 9% think the government adds fluoride to our water supply for sinister reasons, 4% believe lizard people control our societies, and 11% believe the US government allowed 9/11 to happen.
  • We know how crop circles are formed, and yet some people are determined to see them as the work of extraterrestrials. Most of us have probably used Snopes to investigate a suspicious story passed along by email, and yet urban legends continue to deceive.
  • We’re surrounded by simple instances of probability, and yet we’re terrible at it. If you want to see how good your instincts are, give the Monty Hall problem a try.
  • We have cognitive biases such as confirmation bias, where we focus on evidence that confirms our thinking and ignore evidence that refutes it.
  • The weighty Diagnostic and Statistical Manual of Mental Disorders (DSM) lists hundreds of kinds of mental illness.

Now that we’re on the same page that the human brain is imperfect, how do the atheist and theist proceed from here? Turek’s line is, “If you’re an atheist, you can’t justify reason.” So therefore the Christian can?

This is just another argument of the form “Ooh! Ooh! I know! It was God!” No—your unsupported dogma isn’t even in the running. Show us the evidence, or remain at the children’s table.

Evolution selected for animals that had a good understanding of reality. Those that didn’t—those whose senses gave unreliable information and whose brains evaluated the information poorly—became lunch. (I respond to Alvin Plantinga’s similar Evolutionary Argument Against Naturalism here.)

The human mind is indeed unreliable for finding absolute truth. The best we can hope for are good approximations. If Turek can access absolute and immutable truth, he needs to share that marvelous fact with the rest of us.

If we agree that the human brain is imperfect, why does the Christian trust it when it makes the incredibly outrageous claim that God exists? Apparently Turek thinks that atheists can’t rely on God’s imperfect gift but Christians can.
