Tell HN: Ate Food Inside Brazilian Ballot Box, Got Ads About It
3 points by LeonTheremin 1325 days ago
Yesterday was election day for Brazil and I decided to do a little experiment.

I asked someone to purchase 2 different types of food at the supermarket, bag them so I could not distinguish what they were and put each in one of my pocket, separately.

I went to vote as normal, without smart devices on me, as the law prohibits bringing them to the ballot box.

I then picket one pocket at random, draw the content and proceeded to eat it while casting my vote.

After exiting, I got rid of the content on the other pocket without looking at it.

Back at home using my phone (which I didn't take with me), didn't take long for LinkedIn to start showing me related content: as what I ate was a cookie, LinkedIn suggested content about "browser cookies" with a big splash image of a cookie. The irony being that it was an article about privacy.

Twitter showed me ads for a drink brand with cookies on the background.

On news websites, while checking election results, I got ads for competing brands of cookies.

I am tempted to conclude that Big Tech's spying likely lets them know on who I voted and the only reason it isn't explicit that they do is because all political ads are prohibited on the day of the election, otherwise I would have seen ads for the candidate I choose.

Will your "Institute Legal Voting" organization[0] be publishing any data on this experiment? Do you intend to draft a research paper with your findings, or have any documented proof of this happening?

Not currently, need more work done.
Single data point with a spotty read of the outcome should not be enough to put any weight behind a theory.

Chances are "big tech" advertises popular brands, both items in your pocket are likely to have fit into that category.

What am I reading...
an example of confirmation bias.
I can't tell if this is satire.
