I also dug out some old books on ESP and the paranormal. These were from the 1970s, about the time of Uri Geller and the Bermuda Triangle. It struck me that the debate here seems to have moved on, in the sense that no-one any longer takes seriously the idea that ESP etc might be real in the same sense as (say) radio waves, and was a reasonable subject for scientific investigation. The exposure of Geller as a fraud, his subsequent career in the back pages of the Women’s Day and the derision visited on the scientists he fooled with his conjuring tricks seem to have put an end to all this.
Of course, there are still plenty of believers but the belief is now general recognised as quasi-religious and therefore not subject to refutation by empirical evidence.
At least that’s my impression. I’d be interested to hear whether others see thing shte same way.
