AI Thread Summary
The discussion revolves around testing for extrasensory perception (ESP) using two online tests. Participants express skepticism about the validity of the probability statements used in these tests, particularly noting that achieving a success rate over 20% in trials raises concerns about the reliability of the results. One user mentions that their results indicate a clairvoyant ability in a random number generator, which they find unsettling. The conversation highlights the potential for statistical anomalies and the need for rigorous comparison with other random number generators to assess the accuracy of the tests. Overall, the thread emphasizes a critical view of ESP testing methodologies and the interpretation of results.

Test your "ESP"

Just for fun folks.

I am getting the feeling there is something wrong about the probability statement used in this one. In 7 out of 10 trials I did, pressing only the square card 10 times, I acheived over 20% success rate. I smell a rat... or maybe I'm just very lucky

Probably a fairer test is to compare results with that obtained by another RNG...



In the second test, It judged me as having no evidence for esp, but told me my calculator RNG was clairvoyant. Which is pretty disturbing.

20% is the expected result - 1:5 for any card. Why do you think that something is wrong?
 
Because in my placebo run I got consistently better than expected. Though this can be just a statistical fluke.

Lies, damned lies, and...

Thread 'Status Update by JRMichler'

Just ONCE, I wanted to see a post titled Status Update that was not a blatant, annoying spam post by a new member. So here it is. Today was a good day here in Northern Wisconsin. Fall colors are here, no mosquitos, no deer flies, and mild temperature, so my morning run was unusually nice. Only two meetings today, and both went well. The deer that was road killed just down the road two weeks ago is now fully decomposed, so no more smell. Somebody has a spike buck skull for their...
