How about this working theory. PSA and JSA are 85 percent correct (example percentage, don't take the number too seriously), which means a PSA letter says there's a 85% chance the item is authentic. If potential buyers say a LOA on eBay as saying there was an 85% chance, and not 100% guarantee, the autograph is authentic, they'd say "That LOA gives good odds, but I should look into thing further to bridge the gap." Looking into it further may include getting other opinions, educating themselves, looking at who is the seller and perhaps even spend accordingly less money. They will also realize that if they go strictly by LOAs, they will be buying fakes from time to time, because 85% isn't 100%. The significance will sink in further when they realize the TPA's aren't 100% accurate and don't give refunds for the autographs.
