I decided once again, to calmly analyze the situation with Jackowski and activate some healthy skepticism...
It is true that Jackowski has a lot of praise and thanks for finding the body or helping to solve a criminal case. On the other hand, there are no unequivocal cause-and-effect relationships between his actions and skills and the resolved matter.
Also, the very existence of clairvoyance is only a theory. I am not saying that the possibilities of clairvoyance are not possible, nor are I saying that Jackowski does not have skills that go beyond those of a normal person. I do not know that.
As for Jackowski's predictions on Polish and global issues. What he says is very slippery and opens the way to various cognitive biases. One of them is to compare the events that have occurred to those that are predicted in the vision so that they appear the same. As predictions of world change are VERY GENERAL, it is possible to find one or more events that can be matched to give the impression that they are exactly what was foretold
Another thing to consider is Jackowski's charisma. Jackowski makes a good impression, which may lead to a certain heuristic that affects the evaluation of what he says. The fact that Jackowski makes a good impression also means that we evaluate his words higher, which does not have to result directly from the merits of what he tells us.
The next thing to consider is the mere existence of probability. It is just that things happen naturally, with a certain frequency of occurrence. For example, I would say: "This year there will be a big storm! It will tear down the roofs, in one of the villages in the south! I see a big panic! People are angry with the authorities!"
What I said is really just plain probability. It is autumn, and soon winter, it is a period when intense storms can naturally occur with a certain degree of probability. Likewise, with a fairly high degree of probability, I can think that there will be some feuds between the authorities and the people, simply because, statistically, such feuds happen quite often when people are homeless and emotional.
It is the same with the visions of clairvoyants. They can say something that just for statistical reasons is entitled to happen, and then they will credit themselves with superhuman abilities
Finally, I would like to add that I am not saying that Jackowski DOES NOT HAVE any above-average skills. On the other hand, due to the available premises, documents and opinion about Jackowski, it is not clear, one hundred percent, that this man has any supernatural abilities and influenced the solution of any of the matters he boasts.
Also, his predictions on world topics are uncertain. Which does not exclude that Mr. Jackowski has clairvoyant skills. But I have nothing to say that it really is. Jackowski's prophecies and his videos that appear on his YouTube channel. Personally, I perceive it as entertainment content. I believe a better approach to predicting the future is to collect as much reliable data as possible and analyze it appropriately based on logical reasoning abilities. Which is also a better approach: a job well done based on facts and analysis bears more fruit than speculation, intuition, and other forms of guesswork that are not proven fact.
