OK Cupid also has questions covering:

- Evolution.

- Whether or not dinosaurs were a thing.

- If the Moon landing happened.

- The relative size of the Earth and the Sun.

- If Astrology is scientifically accurate.

... among others, all of which I had marked, with the correct answer set as "mandatory". If someone answered enough of these with the wrong answer, you won't even see them (if you do, you'll have a high "enemy" percentage), so you won't waste your time talking to them.

The moon landing thing would be important to me.

I have been on a date with a conspiracy nut, and can confirm that this is something I'd want to filter out if I was still dating and not in a long-term relationship.

They actually instrument the process of setting up your own personal information 'bubble'? 1984 was 30 years ago, so its probably overdue.

I wouldn't use the term "information bubble" to describe this sort of filtering. It's not as though a person is unaware of those who believe differently regarding topics like evolution or the moon landing, or will never hear those arguments. It's just not necessarily a good idea to try to form a romantic partnership with someone who you don't respect because they believe a position you consider to be "crazy".
