I suggest that there is a certain fraction of the population who believe that their opinions are, simply, better than those around them, and some of them have money. Since these folks are successful, they fail to recognize that competence in one field has no guarantee of competence in another. Think of it as a form of Dunning-Kruger, where knowledge of skill in one area is misapplied to mask lack of skill in another.
The memo in Post 1591 (thanks greatly, halleyscomet) has what I consider a statement which seems innocuous but is quite revealing in terms of what if shows about the author.
the absurd resistance by the scientific community to Dr Mills theory
Reading between the lines, the author has no scientific background - he's finance. But he's been convinced, and he knows better than them.
Rejecting "the scientific community" and its opinions is, of course, anyone's right. Creationists are famous for it. The author of the memo is clearly doing the same. Rossi supporters did it. Santilli supporters do it. Markie does it. (The birds and the bees do it. Sorry - couldn't resist.)
But consider the consequences. The memo reports that the investor's mood was "tense", and that they were apparently beginning to suspect that they had thrown their money down a rathole, hence Mills broaching the issue of the secondary liquidity market. I suspect that the "tension" among the investors is directly related to how long each has been an investor. Folks like Markie are new to the game, and have no personal experience with being strung along. Dazzled by the potential market, their greed (either for money or for being in on The New Revolution, When Everything Changed, or both) allows what is known as selective inattention. Of course, there's a Bell Curve for almost everything, and that includes credulity. Hearing the same old excuse time after time gets to be wearing, and I suggest that the investor ages have something to do with it. It's one thing to make a risky long-term investment. It's quite another to realize that you will probably die before (rather than) you get a payout, and letting someone flim-flam you for eternity is a galling prospect.
