I remember my sociology textbook explaining that sports often show what a group values.
Of course that's what the sociology textbook will say. Otherwise what's the point of sociology?
In particular I think that being a rationalist means that you can choose a sport based on it's merits instead on the values it's projects.
What do we want?
-A low rate of accidents
-Cardiovascular benefits
-Muscle development
-Coordination and control over muscles.
-Social interaction
-Developing confidence
That calls for a poll. I take the freedom to add some points to your list.
In the poll below don't assume that all attributes must fit to a single sport but instead might be matched by a set of sports. Best not to imagine a specific sports idea but rather what you require of proposals here.
Rationalist sports should...
have a low rate of accidents [pollid:707]
have cardiovascular benefits [pollid:708]
aid muscle development [pollid:709]
train muscle and motion control [pollid:710]
include social interaction [pollid:711]
help develop confidence [pollid:712]
include...
This post is a bit of an experiment; Most of the time, Discussion post lay out an idea and this idea then get commented upon. This post, on the other hand, will be purely about discussion on a topic. If this works out well, I'll might post more of these in the future.
On to the meat of this post:
I got this idea from a reddit post on /r/LessWrong.
To quote:
So have at it.
I only ask for one thing and that is to hold off on proposing solutions for 24 hours before giving suggestions for actual sports. In the first 24 hours, please discuss what makes current sports unappealing to rationalists and what aspects a sports designed for aspiring rationalists should have.
Edit: The 24-hour window has closed and solutions and suggestions can now be given.
