I'm tempted to put this in the same bucket as "the bell curve" that it uncovered a factoid, but one which shifts the centre overlap of two curves by a statistically significant (ie, measureable) amount, but does not strongly suggest that close to normal people on average have a difference which matters a damn.
Many of us outside google believe that google employs too many people who think they are Mensa, and so self-identify in the far right side. Sorry guys, but I hate to tell you this: your own curves probably don't support your arguments: you're all well within normal.
Those are weak cites (ok: so I gave none) -one has bars wide enough to drive a low-IQ truck through. The other is "I went to IQ camp and here is my cornflake box toy" response.
Having GI is good for engineering, sure. But having maths higher than verbal skills, I think its in the margins. You want both, and people with both, and with determination and good teaching will go far. I believe good teaching and a drive to success outweighs almost everything else.
(not an engineer. I looked at my competencies and decided not to make bridges, I didn't want the burdens which come with being wrong about the bridge building)
The preponderance of the evidence is against you, but I'm not versed in grabbing psych links.

That is very powerful. I would partly agree, in that those are very powerful. I think Liana K makes a very good case that there is something societal going on.
Google employees are well to the right side of the bell curve. Go to the airport if you want to see what normal is. How many of the people there could work for Google? Then consider that those are people who can either afford to fly for leisure or whose jobs are important enough that work is paying for them to fly.
Also, I'd imagine the extremes matter more for cognitively demanding tasks.
>but does not strongly suggest that close to normal people on average have a difference
A valid point, but that does not apply to Google engineers because their hiring practices directly discriminate for ability, as they select the best ~15% of people they interview. Statistically, someone with better than normal ability is far more likely to receive a job from Google than 'normal people on average'.
I contend that even seeking to select for the best 15% they are unlikely in practice to get people who actually lie outside a range we'd consider normal. Not the least because I believe a significant number of the savant are functionally unable to survive an interview process which extends beyond the machine.
The above-normal extends from the mildly interesting to the truly unbelievable. Perhaps I'm seduced by the latter and you want to consider the former. I'd agree that google and like companies hire above-normal. I still content that the profile of ability is probably within spec of normal, even if they aim high.
I hasten to add, I doubt I'd pass a google interview. Haven't tried, don't expect to be tapped. And, I know many fine current and ex- google people and they are smart. The thing is, they all show remarkably high verbal skills, men and women both. Which makes me (bias alert: particular to general warning) wary of a measure which implies there is a detectable skew. These people, display both abilities.
You are playing word games with the phrase ‘considered normal’. The phrase has different meanings whether you consider it from a statistical (as the submitted scientific paper would) or colloquial (as you are) standpoint.
Google does not publish hiring statistics, but I genuinely believe most Google engineers are hired from the top 5% of the general population. In a statistical sense, that could be considered as above normal. However, in a colloquial sense, there is no clear definition of what is ‘considered normal’, hence you could consider persons with top engineering ability as normal. Heck you could even correctly consider everyone as normal, and therefore all Google engineers are normal.
Since this thread is about a statistical interpretation of a population in the US & India, I hope you can see how your use the colloquial sense of the phrase is misleading here.
Interesting you chose 5 and others say 15. because, 15 is close to 1 std deviation. So, my sense that at 15% its likely that people are basically normal, is a crossing point of what the statistics say as a heuristic, approximate signal, and common colloquial meaning. somewhere at 15-20% its really not a big deal to be in that space.
you went 5%. thats the tip of the iceberg. if google can succeed in hiring only from the 5% and get no fake-it-till-you-make-it, or mismeasures, Then sure: its beyond normal in any sense we know.
I'm not a believer. I don't think they can hire to that at the scale they want to be, and not break a huge barrier of cultural assumptions about scores, and measures. They can certainly hire only the top 5% or 1% by degree outcome, and I'd believe they do that too.
I am sorry, but you are still making the same mistake I pointed out earlier, conflating statistical concepts with colloquial ones. You don’t seem to understand the point I am making at all. To understand a statistical argument like the paper submitted, or respond to the statistical argument in the ‘diversity’ memo, you require a basic understanding of statistics. 5%, 15%, those exact numbers I was throwing out, are meaningless here. From a statistical standpoint, what matters is the distribution. The distribution of traits for individuals at the 50th percentile (using whatever metric), is not the same as the distribution of individuals at the 85th percentile, nor the 95th percentile. What you need to understand is that for the general population, the distributions of traits are not identical at every percentile. That is the key misunderstanding you demonstrate in your original comment. Further, your claim that “somewhere at 15-20% its really not a big deal” is not easily disprovable, but statistical nonsense (that’s a colloquial statement).
I do encourage you to re-read my comments and understand where 15% and 5% come from. They are from different populations, something which you do not appear to notice.
Sadly there’s a litany of basic mistakes in your comment. It’s not worth my teaching people high school statistics, so I won’t be replying.

TL;DR no, this doesn't support the diversity memo
