Because there are not many textbooks on the subject, as a rule of thump, papers and other texts are the go-to. Here is a list of literature on the subject which I found to be particularly helpful. Pull requests are welcome!!
[1] Thaler, Richard H., Behavioral Economics: Past, Present and Future (May 27, 2016). [pdf] ⭐⭐⭐⭐⭐
Extra: Thaler himself gave a lecture with the same title. The record is also available on Youtube.
