cognitive reflection

Some of the basic attributes required to handle numbers are virtues such as patience and curiosity. For example, consider the trait psychologists call “cognitive reflection”. A classic test of this ability is the question: “If it takes five machines five minutes to make five widgets, how long would it take 100 machines to make 100 widgets?”

Almost certainly, an answer popped into your head: 100 minutes. But then you probably paused for a moment and worked out the correct answer. That moment of reflection is often missing when we deal with politically fraught claims in the media, or in our Facebook feeds. If the claim slots into our preconceptions about the world, we accept it and perhaps repeat it. If it challenges us, we reject it instinctively.

We need to train ourselves to stop and think. That isn’t easy, because neither the dark art of political rhetoric nor the context-stripping of social media is conducive to a reflective state of mind.

The sex steroid testosterone regulates reproductive behaviors such as intra-male fighting and mating in non-humans. Correlational studies have linked testosterone with aggression and disorders associated with poor impulse control, but the neuropsychological processes at work are poorly understood. Building on a dual-process framework, we propose a mechanism underlying testosterone’s behavioral effects in humans: reducing cognitive reflection. In the largest behavioral testosterone administration study to date, 243 men received either testosterone or placebo and took the Cognitive Reflection Test (CRT), that estimated their capacity to override incorrect intuitive judgments with deliberate correct responses. Testosterone administration reduced CRT scores. The effect was robust to controlling for age, mood, math skills, treatment expectancy and 14 other hormones, and held for each of the CRT questions in isolation. Our findings suggest a mechanism underlying testosterone’s diverse effects on humans’ judgments and decision-making, and provide novel, clear and testable predictions.

That explains a lot...

I gave my boss the Cognitive Reflection Test

It’s really fun to see how people go about answers and their reaction to the actual answers. If you want to try it out:

A bat and a ball cost $1.10 in total. The bat costs $1.00 more than the ball. How much does the ball cost? _____ cents

If it takes 5 machines 5 minutes to make 5 widgets, how long would it take 100 machines to make 100 widgets? _____ minutes

In a lake, there is a patch of lily pads. Every day, the patch doubles in size. If it takes 48 days for the patch to cover the entire lake, how long would it take for the patch to cover half of the lake? _____ days

NO CHEATING! Let me know if you know the answers!
