PS Feel free to ask whatever's most pressing to you - don't worry about whether it's relevant to other readers or not.
Update Jan 2016: We're no longer checking this thread for new questions!
Please ask on our Linkedin group instead: https://www.linkedin.com/groups/5057625
We do try to rate careers based on their 'advocacy potential' (basically how promising is this career as a way to spread important ideas), listing some of the most promising of those we've considered here: https://80000hours.org/career-guide/strategy/strategies/advocacy/
However, more broadly I think this is a very difficult question. You can narrow down to a plausible short-list, but after that it's all about personal fit (i.e. choosing the area where you have the highest chances of outsized success).
It's also worth bearing in mind that success in almost any field translates into some measure of influence, because success gives you some combination of credibility, money and connections. So again, personal fit could be the key thing to focus on in the medium-term.
The short-list would be things like:
Maybe teaching too, though the scale seems somewhat less than those above.
