I think the reason tech guys (some of them) support Rossi is they anthropomorphise. After all, no normal tech guy would do these stupid things. Or, if they did, they would be knowingly a scammer. Rossi seems so convinced of his own correctness that you somehow want him to be an unknowing deluded scammer. And people think - he is a clever guy - he could not be so deluded.
Well I don't claim to know whether Rossi is deluded, or deliberately faking measurements, or some combination of the two. I am certain that giving any credence to theories based on a psychological analysis of what Rossi would or would not do is highly unwise. We know he has done many weird and unusual things. And we know people can be very surprising. Thinking you have managed to work him out with any great confidence shows arrogance or stupidity.
