Ask HN: East Coast Vs West Coast: Risk Adversion

I've been meaning to ask this on here and wondered what your thoughts were on this.

I live (currently) on the east coast, but visited the west coast (SF to get to the point).

After 25 years of living on the east coast, I've started to see a trend of folks here regarding joining/starting a startup venture.

I talk to countless individuals (tech and non-tech) would refuse to leave a cushy 9-5 job to start something awesome.

I recently spoke to an advisor of my startup who mentioned individuals living on east coast (generally speaking) are very risk adverse as compared to SF Bay area (and surrounding areas).

Is this a location thing? e.g. East coast being disproportionally risk adverse as compared to its west coast counterparts? Or have I just met overly risk adverse east coasters?
