I remember way back in 1988, I knew a girl (Kaela Kiernan) getting a PhD in psychology at Yale. She told me everyone was excited by Kahneman et al's Judgement Under Uncertainty: Heuristics and Biases, a collection of essays on cognitive biases.
I found it fascinating, as most people do when they first read about these quirks. You instantly start seeing them everywhere and look for more.
Freakonomics made the application of these biases academically respectable in econ, and have become hackneyed templates for journalists. 'Biases' explain why people do too much or little of everything, and especially, why not everyone agrees with you. https://bit.ly/2J54pSK
