One interesting place to start is Harvard's "Project Implicit". They have a massive publication list[1] and you can even test your own implicit reactions[2].
There are plenty of other scientists testing things like whether people judge women as less competent. A quick google search pulled up a PNAS paper where they did an experiment on women in science, for example.[3]
This is just the tip of the iceberg, of course. There is a whole host of related work, testing other sorts of biases and using other methodologies. I'd suggest a search on your favorite academic search engine for "implicit bias".

You disappoint me, sir. I had such hopes of finding something new and interesting, only to discover that your mere vagueness led me astray.
So even if we arbitrarily exclude a perfectly valid psychological technique because it "doesn't impress you", there's still the matter of my third link. Didja click it?
EDIT: The most surprising part of the PNAS study, to me, is that people who agreed with statements like "Discrimination against women is no longer a problem in the United States" were statistically more affected by implicit gender bias.
"You assert that these studies exist, but you don't bother to identify them for those of us who are not au courant with the journals in which they presumably appear. Would you care to link at least a representative example of the studies to which you refer, so that those of us who are unimpressed by argument from authority may examine them for ourselves?"
The semantic value of these two rather long sentences being identical with that of the two words I actually posted, the only apparent reason to choose the former over the latter would be an interest in pandering to your prejudices. I harbor no such interest, and therefore feel no urge to replace what I did post with what you seem to prefer I post.
All that aside, the request stands. Do you intend to cite a representative sample, &c., or do you prefer to settle for the bare-faced argument from authority you've made so far, without even bothering, as I gather is customary in the use of that fallacy, to name the authority from whom you are arguing? "Studies suggest," after all, is rather weak tea.
Finally, there's probably a name for the fallacy inherent in tossing out an unsupported assertion followed by " -- now prove me wrong!", the way you're also doing; I can't be bothered to look it up, though. Between trying to find the studies to which you cannot possibly have referred more vaguely, and trying to do the impossible by proving a negative, I've got too much on my plate already; you'll just have to find the name for that fallacy yourself, I'm afraid.
