How about the consideration that, out of all good futures that suffer from a tragedy-of-the-commons type problem, those that implement reward/punishment precommitments are more likely to overcome the free rider problem and actually work? Does this not push the probability up somewhat?
I've been talking to a variety of people about this recently, and it was suggested that people (including myself) might benefit from a LessWrong discussion on the topic. I've been thinking about it on my own for a year, which took me through Neuroscience, Computer Science, and International Security Policy. I'm hoping and finding that through discussion, a much greater variety of options can be proposed and considered, and those with particular experience or observations can have others benefit from their knowledge. I've been very happy to find there are a number of people seriously working towards this already (still far fewer than we might need), and their deliberations and learning would be particularly valuable.
This is primarily about careers and other long term focused efforts (academic research and writing on the side, etc), not smaller incremental tools such as motivation and akrasia discussions. Where you should be applying your efforts, now how (much). Unless there's a lot of interest, it might also be good to otherwise avoid discussions on self-improvement in general and how to best realize these long term concerns, bringing those up elsewhere or in a seperate post.
A few initial thoughts:
