Although everyone hear knows I am a headhunter who teaches a bit of Quant
C++, I still amd registered as a journalist, doing occasional pieces for the technical press.
Thus I get press releases like this article, which was merely slightly edited by a cheap hack or maybe an intern to go in a major newspaper
I guess it's true, but given that quantnet has an international audience, I have to query how that plays across different types of people.
On a young white person, I believe this result.
On a fat old white man like me, I think they make you look older still which is probably not good.
On a man whose recent ancestry was India/Pakistan, I believe that it can easily make you look too geeky.
For a similar woman they will usually make you look less pretty which is a maximisation issue. A woman applying for a 'real job' has an optimum prettyness, too much and she risks being seen as not serious, too little and she gives up the advantage she gets from being female. That's not just a male-boss thing, women are on average more judgemental than men on appearance.
I don't think they do anything for someone who looks Chinese/Japanese, my call is slightly negative, more so for females.
Black people I think get helped by glasses most. There's still enough racism lurking about for them to benefit from anything that makes them look smarter.
But a lot goes to the glasses. Anything with a logo than can be easily seen is a bad move, and thick lenses can make people associate you with mental defectives.
Also of course, don't try and wing an interview without glasses that you need, people will misinterpret your optical squinting with dumbness.
Of course this stuff is entirely subjective.
