It seems like a lot of people act surprised or upset when they talk about their "powers" here and are met with skepticism from multiple members of U-M. I frankly have to wonder why people would be surprised at such a thing.
Firstly, we need to understand the way the world works.
The world is full of all different types of people who believe all different types of things and feel all different types of emotions, and so on. Now, there's definitely no shortage of people in the world who would agree that the human mind is capable of doing magical and unexplainable things. However, in the modern era of science and reason, there are an increasing number of people who want evidence before they will believe what you're saying.
Nobody inherently deserves trust.
When someone makes a claim that they have a psychic power, it collides with the reality that most of us have been living in and experiencing. In such a reality, it is impossible for the brain to produce magical effects, such as twirling objects, burning things, or accurately guessing what random peoples' favorite color is. It would be the same if I came up to you and told you that your foot is made of jelly. You wouldn't believe it, because you have always understood that your foot is made of blood, bone, muscle, skin, etc.
And you shouldn't believe it! Your foot is not made of jelly! It's good to be skeptical toward things like that, because you have so much evidence saying what your foot is truly made of, and only one quick claim that your foot is made of jelly. It's only reasonable to stick with the scientific explanation.
Now, imagine the brain is our "foot". Many, many people come here and claim that the brain has the ability to perform magic feats. They say: "your brain can do it too!". When you hear something like this, how is it really any different than them telling you your brain is made of jelly? They are stating that the human brain can perform tasks that it has never been shown to be able to perform, and without an apparent means to perform said feat.
So which way do you expect people to sway? In the direction of the person making one quick claim? Or in the direction of hundreds of years of scientific research and evidence? It makes no sense to believe random claims on an internet forum. It ignores the simple principle that the most evident theory is likely the closest to the truth. This is why people ask for a video, or some sort of proof when you do make these claims.
After all, how many people have come on here and said they could do magical things with their minds? Hundreds? Thousands?
How many of those people likely had video recording equipment? Half of them? All of them?
And how many people have offered a video to prove it? Not a single one.
Imagine that I strolled over to this forum claiming with great confidence to have brown hair. I wanted people to believe that I had brown hair... yet nobody would believe me unless I posted proof. What would I do, then? I'd take a quick picture or video to show that I did, in fact, have brown hair. It's a simple process, and it gives credibility to the claim I'm making. Why is this so hard when it comes to psychic powers?
Well, as us skeptics see it, it's because the powers you claim to have do not exist.
You can change our opinion if you really can do it, you just have to be reasonable about it.
