" rather anti-collectivst statement."
That is normal because all fans of Ayn Rand are anti-collectivist.

“...that the whole issue is seeing people as groups rather than individuals.”
That was an rather anti-collectivst statement.

"How can this be prevented?"
Just by focusing on individual rights and achievements.

I think people should seek the truth regardless of what I or anyone else believes.

I haven't read the book, but I recall the controversy. It seemed to me, not having read the book, that the whole issue is seeing people as groups rather than individuals.

Is someone suppressing facts? I honestly don't know the first thing about this. I imagine, though, if I were a researcher wanting to study certain physical traits vs ability to pass a test, I'd pick detached ear lobe and rolling tongue as my physical traits to avoid it being misconstrued as endorsing racial traits being tied to identity groups.

As Rand says, statistical measurements of a collection of people, whether accurate or not, tell nothing about an individual.

IQ does measure something, whatever it is, can be repeatedly measured with a reasonable consistency. Unfortunately as Charles Murray found out with The Bell Curve, publishing statistics which show groups have different means can be hazardous.

“...we shouldn't be dividing individuals into groups in the first place.” How can this be prevented? We are all very different and grouping is used for what we have in common.

I’m sure some people do believe what you state. Does this mean that science in these areas should be actively prevented from finding the truth?

Very true. “Facts” also shouldn’t be made up just because some think it would be more convenient If they were true. This is also a very dangerous precedent. Most of us would not like to live in a world like that of 1984.

I agree with your points.
.
But facts are facts - they shouldn't be suppressed just because they are inconvenient. That is a very dangerous precedent.

The linked text is powerful. I don't have anything to add to it.

" vast differences of IQ scores "
IQ is just what we choose to put on the test and call IQ. Race is the physical attributes that we choose as criteria for race. Correlation between these two groups is compounding the issue that we shouldn't be dividing individuals into groups in the first place.

Maybe the issue is racists wants to say race is real and their race is fundamentally superior. They imagine the IQ test as a measure of worth, and then they can scientifically conclude human value is bestowed more on their race. Those people should go do something they love and value in life and abandon dividing people into groups and putting the groups on scales of merit.

I think the Tew concept in the post is missing a key element. As stated it is a concept better described as racial, not racist.

To be racist would also have to include some fundamental belief that one race is superior to others OR that one race is inferior to others. Thus, justifying actions towards another group that keep them down, based on the people's race.

Simply identifying with others that are of a similar race and background, aka culture, doesn't make you racist. One can be proud to be Japanese without hating Egyptians, etc.

If so, then ANY individual promoting changes to equalize racial groups, is a racist.
