Lawyer, Scientist, or Animal? Choosing Between Evolution and Human Reason

In a post for the NPR blog 13.7, UC Berkeley psychologist Tania Lombrozo asks, “Is the Mind’s Approach More Like a Scientist or a Trial Lawyer?” She praises advances toward greater scientific objectivity, suggesting this holds promise that humans can overcome their natural biases. But the case for scientific objectivity only makes sense in a context where we can trust our reason. And guess what? That’s an assumption more compatible with intelligent design than with an evolutionary framework.

Lombrozo asks whether we tend to reason like scientists — that is, examine the evidence and draw conclusions based on it — or more like trial lawyers — cherry-picking data to fit our case. She notes:

People are capable of impressive scientific thought (indeed, the best scientists are all people!). And at the same time, people are quite capable of fooling themselves into thinking the evidence does support their beliefs, even when a more objective assessment would suggest otherwise.

But she offers hope: Science is becoming more objective. Therefore we as human beings could be improving too.

But optimists can point to a critical respect in which we might just be like scientists. Science is continually reinventing itself: We develop new statistical tools, better practices and better theories.

As one example, some scientists have recently adopted a practice called “blind analysis,” which guards precisely against the kinds of confirmation biases that could otherwise influence scientific research. With blind analysis, scientists make all decisions about how data will be analyzed prior to seeing the data itself. As a consequence, these decisions can’t be guided by their expectations or preferences about the conclusions the data will ultimately support.

If we’re like scientists in this sense — in the sense that we can recognize problems with our thinking and develop better practices, at least some of the time — then there’s room for a more optimistic view of the human mind. Instead of fooling ourselves into believing what we expect or want to believe, we can develop better ways to get ourselves to make the best decisions — be it through education, artful nudges or better technology.

Blind analysis is a good idea.

But notice this. Lombrozo places her confidence in science — a human endeavor — to reveal truth about the universe. Is that confidence justified? Well, it depends. Judging from her earlier blogging, Lombrozo seems to be in favor of materialistic evolution, but that same viewpoint undermines our trust in reason, or ought to do so if you’re consistent. In The Magician’s Twin, John West describes C.S. Lewis’s views:

The scientific method is premised on the idea that “rational inferences are valid,” but the Myth [of materialistic evolution] undercuts human reason by depicting it as “simply the unforeseen and unintended by-product of a mindless process at one stage of its endless and aimless becoming. The content of the Myth thus knocks from under me the only ground on which I could possibly believe the Myth to be true.” Darwin’s own gnawing doubt rears its head yet again: “If my own mind is a product of the irrational… how shall I trust my mind when it tells me about evolution?”

Lewis is joined in this argument by Nancy Pearcey in Finding Truth: 5 Principles for Unmasking Atheism, Secularism, and Other God Substitutes, and Alvin Plantinga in Where the Conflict Really Lies: Science, Religion and Naturalism.

Darwinism, in other words, undermines itself as a scientific idea. It asks that we trust the theorizing done by human minds, yet tells us those minds are a step away from irrational animals. How did trustworthy reason “evolve” ex nihilo? Materialists sidestep that conundrum.

But if study of the universe reveals evidence of intelligent design, we may have reason to trust our minds after all. Yes, sometimes we evaluate facts objectively and revise our actions accordingly — while other times we look for data that supports our preconceived notions. Scientists included.

Under materialistic evolution, we are neither scientists nor trial lawyers — but animals. Under ID, at least there is the chance of human beings exercising right reason and, on that basis, making real scientific progress.
