Waller: If there were really such a thing as extrasensory perception, it would generally be accepted by the public since anyone with extrasensory powers would be able to convince the general public of its existence by clearly demonstrating those powers.
Waller's Claim 1
If there were ESP, public would generally accept
does Chin argue that Yes, it seems like Chin does argue that. He lays out a scenario in which the influence of the elite would lead the media and thereby the general public to remain skeptical and not accept ESP.
Waller's Claim 2
Anyone with ESP could convince the general public of ESP by clearly demonstrating their powers.
does Chin argue that, Yeah, kind of. Our author thinks that the influence of the elite would bias the media which would bias the general public against accepting ESP.
Waller's Claim 3
Anyone who was recognized to have ESP would get rich and famous as a result.
does Chin argue that, No. Chin doesn't get into this hypothetical of what would happen with someone who was recognized to have ESP, mainly because Chin is pessimistic that the general public would ever accept that someone has ESP.
Goal
They seem to disagree about whether the public would generally accept ESP, if it actually existed, and whether someone who possessed ESP could convince the general public by clearly demonstrating those powers.
