There have been numerous tests made regarding things like telepathy and precognition. No properly designed test (true double-blind) has provided evidence in favor of telepathy and precognition.
1. In an earlier post, you claimed that the bias against funding tests of telepathy was justified because
"Precognition and telepathy and creationism all fall into the same bucket - woo. That is why their proponents are not taken seriously." Now, in contradiction, you're claiming that there have been numerous failed tests. Who funded these "numerous" failed tests?
2. The fact is that the few tests on telepathy that have been done have been the topic of intense controversy because they showed positive results. If they hadn't shown positive results there would be no controversy.
For example, the positive results of the Ganzfeld tests were challenged because it was possible that the staff, without knowing it, transferred clues from the sender to the receiver (there was no evidence of cheating or a credible theory of how this transfer might have happened).
The challenge resulted in the Auto-Ganzfeld tests which automated the process and eliminated the staff. It also showed positive results which were then challenged on the math employed.
As part of this test, subjects who showed telepathic ability were tested against subjects chosen randomly. And, those with ability scored higher no matter how the math was done.
In many cases, tests have shown that the people claiming to have telepathic powers or being capable of precognition are either deluded or are out and out frauds.
I know of no such tests but your claim is common knowledge. Yes, of course, people can be deluded and others make fraudulent claims. So what? Why should this be considered evidence to support your argument that telepathy and precognition are not real phenomena?
