The problem with claims of telepathy is that they disappear when actually tested with sufficient controls to disallow cheating. Have a look at James Randi's Paranormal Challenge: https://en.wikipedia.org/wiki/One_Million_Dollar_Paranormal_...

Your "scientist" seems to be somewhat of an idiot - that particular telepathy claim could be fairly well tested with a supply of sick and well kids and sufficient barriers to prevent sound/sight/smell from providing clues to the kid being tested. It's the kind of double-blind test that has been used to test if dogs can diagnose disorders e.g. Parkinson's.

Interestingly, there's a woman who can detect Parkinson's through smell alone. When she was initially tested (double-blind sniffing of t-shirts that had been worn overnight) she identified all the diagnosed Parkinson's sufferers correctly, but also diagnosed one other person. However, a few months later, that participant was also diagnosed with Parkinson's which means that there should be chemical markers (that produce the scent) that could lead to early diagnosis.
