[Question] When is positive self-talk not worth it due to self-delusion?

This is a pretty funny and quick TED talk about positive psychology that I liked, though I wish it addressed the possibility and harms of self-delusion more.

Questions I now have about deliberately choosing positive thoughts:

  • How harmful is the self-delusion from choosing positive thoughts?

  • What does this self-delusion look like, e.g. what are some detailed examples?

  • How should we account for the dynamic that thinking more positively will actually make outcomes more positive, given that positive thinking makes you more productive in various ways?

  • What does it mean for your emotions or thoughts to be “more negative or positive than is granted”?
