An important goal could be to increase rationality in the world. I believe that would do more good in the long term than trying to solve aging. The best way to achieve that through this suggestion box would be an idea that is simple and direct and hard to get wrong.
For the first two points (simple and direct) better education would help. How about improving science classes by including actual science, that is, learning to change your mind and to look at evidence. However, I fear this will be very hard to get right, and hard to get accepted by teachers. Does anyone have other suggestions for improving rationality?
How about teaching self-experimentation?
This is interesting about creativity and project-oriented education.
The question that the ideas are supposed to be in response to is:
Here are links to some proposed ideas that you should vote for, assuming you agree with them. You do have to register to vote, but the email confirmation arrives right away and it shouldn't take much more than two minutes of your time altogether. Why should you do this? The top voted ideas from this request for ideas will be seen by some of the top policy recommendation makers in the USA. They probably won't do anything like immediately convene a presidential panel on AGI, but we are letting them know that these things are really important.
Research the primary cause of degenerative diseases: aging / biological senescence
Explore proposals for sustaining the economy despite ubiquitous automation
Establish a Permanent Panel or Program to Address Global Catastrophic Risks, Including AGI
Does anyone have any other ideas? Feel free to submit them directly to ideascale, but it may be a better idea to first post them in the comments of this post for discussion.
