I have found our original discussion, it was 57 days ago. So let's do another analysis of their timeline two months ago (December+November, for example). But this time, you tell me how to categorize their tweets.
For example, should this picture count? It is not somebody working at Google, just a stock image of somebody working in the food industry: https://twitter.com/lifeatgoogle/status/813410799725215744
And how should pictures like this be counted: https://twitter.com/lifeatgoogle/status/800818789122129926 or this https://twitter.com/lifeatgoogle/status/812002215267139584
Maybe from the last two you can also see why perhaps simply counting people is not the best metric - a single group photo could distort everything.
You mention you work in statistics, so tell me how you would approach the problem?
Also maybe I didn't express it clearly enough, I didn't look at the whole timeline, only the media timeline: https://twitter.com/lifeatgoogle/media (which is media they posted, pics and videos).
I also didn't claim I can tell bias simply by looking, I said it was my impression they don't want to hire white men anymore. If I was convinced I could tell simply by looking, I wouldn't agree to do an analysis.
As I said - I am sure they still hire white men, but that particular account (and some of their other publications) give the impression they are not interested in that anymore.
And they claim to represent Google's demographic, not the demographics of the general population, so contrary to what you say my numbers do show bias against white men. Not as extreme as I perceived two months ago, but still.
If your company is 70% men and you only report about what women are doing, it is revisionist.
Imagine if all stories about WWII would only be about female soldiers. The impression would be women fought and died for our freedom, all the sacrifices of men would be forgotten. That is revisionism.
