I think the level of prejudice is so high that you'd need a good bit of money and a lot of dedication to do it on the large scale. I keep thinking it would take ten million dollars to start a mass production clothing company, but this is only a guess. Does anyone here have a well-founded estimate?
As for the smaller scale, here's some of what's going on. If you're not up for starting the big company, you might find a small business which is worth investing in.
How sure are you that fat women won't shop at a places that offer good clothing only for fat women? My first thought was that your theory is nonsense, but then I realized I'd been reading fat acceptance material for so long that I don't really know.
Maybe it's just that the hypothetical business would need to advertise.
Those websites have some pretty things. (Including items I wouldn't expect to be marketed to any size in particular - really, scarves?) I wonder how large-scale a movement towards the availability of pretty clothes for plus sizes would need to be before large, pretty clothes started reliably being available in thrift stores? (I have been spoiled by $3 garments and wince whenever I look at retail prices -.-)
I'm trying to better understand the relationship between incentivization and rationality, and it occurred to me that it is a "folk fact" around here that large financial incentives don't make cognitive biases go away.
However, I can't seem to find any papers that actually say this. It's not easy to google for (I have tried) so I wonder if the Less Wrong collective memory knows how to find the papers?
Is there a pattern to which biases go away with incentivization? Do we have at least 5 examples of biases that go away with incentivization and 5 examples that don't go away with incentivization?
As an incentive, I'll paypal $10 to the commenter whose answer is least biased and most useful.
