First off, if you live close to a university or college campus you have an observational case-study in your environment that you need to utilize.
I live in a university town in the midwest and school is now back in session. The freshman just arrived on Thursday. The only ones attending these days, are the brainwashed. It's that simple.

With that said, pay attention to he numbers of students that you see. Dive around and pay attention to the mask wearing. When it makes a comeback, drive around and observe who is complying and who is not.

What I witness here, is it's observably vacant. Hundreds of students walking around, where there were once thousands. Some might blame a lowered birth rate, and while that is true, the shots and illnesses are far more likely, because in 2019 the campus was visibly full. Not now.
There are far less students on campus, with housing on and off campus, than ever before. The rental houses off campus are still for rent and many of them are for sale, where they were once all filled. The last two years saw a dramatic decline in student population, even thought he university lied and said that they have the largest enrollment they've ever had. These places will lie to the end, but your eyes never lie. You can visually see that there are far fewer students on campus. There's ample parking too, where there was once not a single parking spot available anywhere in town when school was in session. The parking lots in the student apartment buildings are also not full, where once they were.

These are the kinds of visual observations that anyone can make and I highly recommend it. Be objective. Take notes. Most students walk around on campus in the middle of the day, when it's sunny and warm out. Take a peak and see what you see.

Where there were once thousands, there are now hundreds.

This winter is going to be a doozy, and these places still use the fake "COVID" tests, and they believe the results.
