About Cognitively Biased

In this course, you will learn a new cognitive bias, effect, or heuristic each day and understand why others (and you) make poor decisions, bad arguments, and hold false beliefs. All cognitive biases in this course are involved in the reasoning process and can lead to accepting bad arguments. The first and most important way to combat the negative effects of cognitive biases is to recognize them. This course will help you do that.

Mitigate the Effects of Cognitive Biases and Become More Reasonable

  • Passive microlearning: receive an e-mail a day on a cognitive bias for 125 days
  • Become a better debater
  • Improve your critical thinking skills
  • Ditch your false beliefs
  • Become smarter

Become a Cognitive Bias Whiz and Understand Logical Fallacies Better

In the early 1970s, two behavioral researchers, Daniel Kahneman and Amos Tversky pioneered the field of behavioral economics through their work with cognitive biases and heuristics, which like logical fallacies, deal with errors in reasoning. The main difference, however, is that logical fallacies require an argument whereas cognitive biases and heuristics (mental shortcuts) refer to our default pattern of thinking. Sometimes there is crossover. Logical fallacies can be the result of a cognitive bias, but having biases (which we all do) does not mean that we have to commit logical fallacies. Consider the bandwagon effect, a cognitive bias that demonstrates the tendency to believe things because many other people believe them. This cognitive bias can be found in the logical fallacy, appeal to popularity.

Everybody is doing X.
Therefore, X must be the right thing to do.

The cognitive bias is the main reason we commit this fallacy. However, if we just started working at a soup kitchen because all of our friends were working there, this wouldn’t be a logical fallacy, although the bandwagon effect would be behind our behavior. The appeal to popularity is a fallacy because it applies to an argument.

When we understand cognitive biases, we understand the reasons behind countless bad arguments, bad reasoning, and bad ideas.
