Facebook's algorithm already has you labelled as liberal or conservative
So you think you've done a good job hiding your politics on Facebook. On your profile, you don't list your views. You don't click "like" on politicians. When your crazy uncle posts rants about how the government is controlling the weather through chemtrails, you ignore him. Nobody knows what you believe, right? Wrong. Facebook has already labelled you liberal or conservative, based on an analysis of everything you do on the site.
We already know Facebook collects information about us so they can target us with ads. If you search for "ice cream," you see a Ben & Jerry's ad. If you search for "concerts," you see a Coachella ad. If you search for "crappy movies," you see a Transformers: The Last Knight ad. I guess we're cool with this, but it seems pretty invasive. It reminds me of that episode of Futurama where companies start beaming ads in Fry's dreams. Shoot, I shouldn't have wrote that - don't want to give them any ideas!
So how is Facebook able to determine your political views? The same way they target you with ads. They can't see the Bernie Or Bust bumper sticker on your car or the Trumpstamp on your lower back (yet), but they can make a deduction based on your user activity. If you "like" Black Lives Matter, universal health care and smokin' weed every day, Facebook might classify you as "liberal." Meanwhile, if you "like" The NRA, NASCAR and giving the richest people in the world tax cuts, Facebook might classify you as "conservative." They can also predict your feelings by analyzing the identities of people who like the same things you do. To quote Tyler Durden, you are not a unique snowflake.
Remember, Facebook has 1.7 billion users, with 204 million in the United States. This information is very useful during election season. For example, in 2020, when Kanye West runs for President, he can create ads tailor-made for specific groups - one for liberals, one for moderates, one for conservatives, one for hardcore supporters, one for the apolitical, one for Kardashians, etc. And that's how Yeezy will defeat his Republican opponent, Kid Rock. (2020's going to be weird.)
If you want to see how Facebook has categorized you, and change it, follow these instructions:
1. Go to https://www.facebook.com/ads/preferences. On that page, you'll see your "ad preferences," divided by category. (And yeah, you'll probably some weird random stuff. Enjoy!)
2. Click on the Lifestyle and Culture tab. (You may need to click on "More." Facebook hides things, like sneaky fat hobbitses.)
3. Look for a box that says "US Politics" with your political views (liberal, conservative, etc.) in parentheses. You can find it by clicking on "Your information," then "Your categories." If Facebook thinks you're liberal, celebrate by marching down the street in a pussy hat. If Facebook thinks you're conservative, celebrate by destroying the environment.
4. To get rid of this information, click the "X." You can do this for all the "ad preferences," if you want to have a blank slate, and really stick it to Facebook. But then you might see ads for "blank slates" and "sticking it to Facebook."
Yeah, this is all pretty creepy, and straight out of 1984. But don't worry, President Yeezy will fix everything in 2020.
