It would be great if one could concentrate on cleaning up a bedroom floor by just thinking about it. Kinesis is movement. To think of an object moving and have it move...that's what telekinetics can do.

Think of the X-men movie. The bad guy (Magneto?) can attract objects to him that are made of metal. They fly through the air at his whim. That's supposedly telekinetic power.
It doesn't happen that way.

The Russians tried like hell to find psychic talents in the 60s and 70s.
They had some people that could bend spoons and move tiny chess sized pieces of metal inches at a time.

Imagine thinking about your cereal spoon and it pops into your hand from it's place by your cereal bowl. Or shutting a metal door in the face of an enemy and adjusting the lock to set with your mind from across the room. That's strictly imaginary, but the spoon thing is possible.

Mostly telekinetics bend spoons in sideshow acts.

There is a dark side to this, however. The activity claimed by poltergeists or noisy ghosts. Actually, the books sailing across a room and dishes dashing from the floor from cupboards, arrows and knives zinging through space...these things can happen and they are probably the work of pubescent children who have the ability to make things move. Usually when they're in a temper.

Usually when they have not gotten their way or when they're bored...these things happen and they have little or no control over it.

I once witnessed someone who was extremely angry in one room send a plate sailing through the air to crash on the floor in the next room.
That can happen. Temper, especially a violent one, can bring about huge telekinetic action. But mostly, it's best observed in movies. In the cinema, all sorts of strange things happen and are credited to telekinetics who in real life would not have these abilities. By magnifying their powers for the screen, they become monsters or saviors.
In real life, telekinetics can't do much more than show their tempers, scare the crap out of mommy and daddy and bend forks and spoons, unless under the watchful eye of television hosts who used to perform magic tricks themselves.

Carl Jung, the philosopher/scientist/psychologist whatever he was, supposedly believed in the supernatural. He tried to convince other people that it existed, that these mental powers were real.
Nobody really listened because if you weren't a charlatan back in those days, you couldn't actually make anything supernatural happen.
He got so pissed that he managed to have two books sail off a shelf and smash together, making a loud noise. When the skeptics went to investigate the cause of the noise, they found the two books on the floor of the empty room with no one nearby. Except a pissed off Carl Jung.

Did it happen? It's supposed to be documented somewhere.

But you have to believe in it.
You have to think there are people who can manage to do this stuff.
Perhaps they can perform these strange, useless feats. Until there is a use for them (how much can you get for banging two books together in public?) no one ought to take the talent too seriously.
But, you say, what if it does exist and people actually can make objects move strictly by thinking about moving them?

Now, that would be worth something.
Somewhere.

It would have to be a tremendous power, able to lift tremendous amounts of weight.
Not just cutlery.
So, here's a picture of Carl, second only to Sigmund Freud in fame regarding psychoanalysis. It must have pissed him off to be known as "second best".
