Thanks for writing this up! I’ve forwarded it to a friend who was interested in the happiness app space a while back.
I would add to the advice, from my experience, pick something not too far out of people’s comfort zones for a startup or research idea. There seems to be a horizon beyond which you don’t get feedback or help at all.
The unilateralists curse only applies if you expect other people to have the same information as you right?
You can figure out if they have the same information as you to see if they are concerned about the same things you are. By looking at the mitigation’s people are attempting. Altruists should be attempting mitigations in a unilateralist’s curse position, because they should expect someone less cautious than them to unleash the information. Or they want to unleash the information themselves and are mitigating the downsides until they think it is safe.
I’ve not had the best luck reaching out to talk to people about my ideas. I expect that the majority of new ideas will come from people not heavily inside the group and thus less influenced by group think. So you might want to think of solutions that take that into consideration.
