Okay, I was made aware of this website a few days ago and it was possible to search Facebook users by many criteria as location, gender, age and IQ.

So If I'm getting this right, now we are all can have the data that Cambridge Analytica was supposed to delete, right?

No. This is Facebook data from public profiles gathered in 2007 to 2010.

CA’s data was collected via a quiz app, from users and those users’ friends, sometime around 2013-2015.

Okay, any idea how this website was able to search by IQ?

No idea. But IQ is not a data point in FB’s system. So likely it’s a data field that’s part of some game/app?

According to this article Facebook can estimate user's IQ: https://www.ft.com/content/3dfa397c-9a73-11e4-8426-00144feab...

Do you think that this could be a FB data point as the creator of the archive claims to have had a deal with Facebook to scrape data?

I can’t read past the paywall. But you read a newspaper article in which someone (who? A FB official? An academic?) claims FB can derive something from user data? That’s something literally anyone can try to do. Doesn’t have to involve FB officially.

Sure, but I would love to see what FB derives from their wast data and userbase.

"Prior to April of 2008, Plaintiffs had written the first Survey, Petition, Polling, Quizzes and IQ Test applications to appear on Facebook and ranked as one of the largest Facebook application developers in the world."

This is public profiles, not friend networks. It's the data that you weren't supposed to publish if you didn't want people to see it.
