The truth has value in decision making, while comforting lies have value in stress reduction. Choosing ‘truth’ over ‘comfort’ is a long-termist strategy. Being satisfied by a simple answer will make you feel better now, increasing survivability in the short term, but finding a better model of the world to operate by, a.k.a. learning, lets you make better decisions for the rest of your life.

More beneficial for whom? The truth is that pollution is bad. I can make myself feel better about how much energy I use by assuring myself that I’m chosen by God and deserve to consume resources and pollute. This harms other people though. The truth is non-opinionated, so actually useful. Believing something to make yourself feel better, and ignoring problems, is biased favoring yourself and against others.

Well I’m not that guy but I can speak from myself that every time I have been true to myself and others, I have felt more and more real and tangible myself. And it is a much better feeling than “fooling yourself” with the why not, using rational logic to just make a decision like that. I always say to my kids, nobody can know what happens when we die and if they say they do, they are making it up. But we can talk about some truths still, that are felt, and then communicated to you as just something that is comfirmed by experience, that is, you experienced something nobody else should know and then they did too, with synchronicity and other phenomenon which just makes us assume it’s true. But in the sense of scientific fact it can not be described because words and language kind of is not enough or it doesn’t kind of translate at all.
