Personal experience and surveys on running out of socks; discussion of socks as small example of human procrastination and irrationality, caused by lack of explicit deliberative thought where no natural triggers or habits exist.
Incidentally, both the GS & Eric Jorgensen polls include some demographics data: estimated gender/age/location for GS, and ESL-speaker/country/gender for Eric Jorgensen. Those aren’t my main interest here, but how do they look?
One could make some predictions based on stereotypes: women will have more socks than men, older people will be more likely to have enough socks than younger people, and there will probably be cross-country differences. Checking, older people are indeed more likely, cross-country differences are not so large as to be inferable, and there appears to be inconsistency in gender effects: men have more problems with socks in the US than internationally?
