Table 3 should tell you all you need to know about ESP.

I would also be a little worried about Table 2. The magnitudes of the Spearman's correlation coefficents are consistently low, whilst at the same time, they claim a very small P-value. This suggests an error in the statistical analysis or an unreasonable null hypothesis.
Unfortunately, the ESP literature seems to be plagued with misunderstanding, misuse, and in some cases even outright abuse of statistical methods.

ESP studies are also notorious for being exercises in confirmation bias. Positive results are submitted for publication, whereas negative results are ignored. The correct scientific thing to do is to report ALL of your results.
Although it has to be said that ESP researchers are not the only guilty parties in this respect, not by a long shot. Pharmaceutical companies do it all the time. It's considered research fraud to cherry-pick data from a drug trial and submit it for publication, so what they do is run many simultaneous trials, and only report on the few that happen to paint the drug in the best possible light.
