Let me explain one reason why this is a potentially serious problem. First, you should know that when I search google from an incognito window it gives me the right answer: just shy of 14 billion years, the current scientific consensus among cosmologists and astronomers.

This means Google is using tracking info – what it thinks it knows about me – to decide which answer it should serve to a question *where there is clear scientific consensus on the answer*. You can see the problem here.

If, based on your browsing, google decides you are anti-vaccine, and you do a search about how to protect your kids from measles, how will it respond? Will it present the medical consensus, or point you to a "study" that hasn't been around long enough for serious review?

What the Nobel Prize fails to mention here, and fails to mention every year, is that both Burnell and Hulse were 24 year old grad students when they made their discoveries. Hulse is a man, so he got the prize. But Burnell is a woman, so the prize was given to her supervisor.

Obviously google searches shouldn't take the place of advice from trusted experts like medical doctors, or, in the case of the age of the Universe, cosmologists. But it also shouldn't make things worse in an attempt to show you what it thinks you want to see.

That would suggest (to me, a non-expert) that it isn’t based on what it knows about me. Both searches are from a regular window. Still, I’d expect a lot less variation in when it serves untested research and when it serves the consensus answer here.

@ThaDrkness Until it has stood up to extended scrutiny from scientists, it is not appropriate to present it on the same footing as the scientific consensus. Folks may not realize that models like this get proposed, examined, and rejected on a regular basis.

I’m a professor of physics. I don’t know any scientists who think Jordan Peterson is the serious intellectual his acolytes make him out to be. I know lots of scientists who see that he is a dangerous jerk with no real understanding of the science he carelessly misappropriates.
