The perception census 👁

Got sent this at work and I’m really enjoying taking part so far! It’s a study about how people perceive the world differently. I just love this stuff.

It ties into @GentleGiant’s question about believing in reality, a bit. I think there is no one objectively true reality that exists outside of the entity perceiving it. Instead I feel like there’s trillions, with everyone and everything’s own perception overlapping and contrasting all the time.


Slightly concerned that it asks for your email address without any information at all about how data will be used/stored?


This looks interesting, I going to bookmark this to go through it after work.

I’ve removed the ‘login’ and there’s still no information on the main page even though it appears to be British based. Is that even legal? Sorry, not meaning to derail, it looks really interesting just want to know what I’m signing up for.

Any way to trick it into working on mobile? Not planning to be at a desktop for a while.

too hot to even do this properly

Ah, ace, thanks. Yes, very strange that they haven’t made it really accessible. Will take a look this evening, thanks for sharing @anon75298087 :+1:

Give it a fake one


great site

Change your browser to ‘desktop site/version’


Sorry yeah, that wasn’t clear was it - I think the reason they give you a login is so you can come back and do bits of the study at a time, as it will take a few hours in one go. Rather than saying “this person with this email address answered X”, but how are you supposed to know that :smiley:

Bah, this is tricky from an ND perspective when you only have how long each section will take but now how long it is overall (finding some of them quite anxiety-inducing too - that video with no time indicator on the bottom made me freak out a bit!) Still want to finish it though :slight_smile:


Yeah I’ve found the sound ones quite hard

Done all of the sections so far

quite satisfying to see that my time perseptions and sound & music perceptions are pretty much on the money

found some of the questions in the body & belief section a bit ambiguous though. Not sure how much was intentional v how much was the bias of the researchers v how much was my own interpretation of language

Wtf! Wild.

Introductory one is pretty fun isn’t it? I guess I’ll do the rest later.

I don’t really have a favourite colour so I just picked one but I guess if they cared they’d have had an ‘I just picked a colour’ box.

I did worse on the shape sizing thing than I expected as I knew the trick so I thought I’d compensated enough.
