Good point Klaynos. Money, a reward and a temptation forever it seems. John Ioannidis, in his now famous article (infamous for some) and many others have cited this problem (https://journals.plos.org/plosmedicine/article?id=10.1371/journal.pmed.0020124).
Two different “methods”? Then show both, if only commenting briefly on the failed method – the glue made this way was sticky for joining paper and wood only, but made this way, with the same ingredients, it was very sticky for paper, plastic, and metal.
But this does not go to the heart of the selective reporting issue, which in my view is essentially this: did you deceive others, did you lie, using the oldest and hardest-to-discover method around, which we all learned as children, long the stock-in-trade of journalists and politicians – hide information; what is not there “doesn’t exist”. I believe that would be fraud. In other words, “selective reporting”, as I understand it, is simply fraud. Or my understanding is wrong.
