The regulators have spoken and they require disclosure. I would guess that about one fifth of the books reviewed here are advance review copies which I did not pay for. They were sent to me for free, by demons who wish to addict me. If am reviewing a book before its publication date, it is almost certainly an advance review copy, sent to me for free.
If I am reviewing a book past its release date, it is only rarely a free review copy. Very often I visit the free public library and walk away with ten or twelve books in my arms. Just this week I ordered two new books for $40 a piece and I would not have bought them otherwise, but for my desire to please MR readers with my timely reviews (which are forthcoming).
I hardly ever receive works of fiction. I am never sent toys or given free trips to Disneyland.
It is reported:
For bloggers, the FTC stopped short of specifying how they must
disclose conflicts of interest. Rich Cleland, assistant director of the
FTC's advertising practices division, said the disclosure must be
''clear and conspicuous,'' no matter what form it will take.
Beware! You have been warned in a clear and conspicuous manner that the demons control me and I do not in turn control the demons.
Addendum: You might wish to read Tyrone on free will. The real scandal is that we (possibly) live in a frozen four-dimensional space-time block and that the content of my reviews has been fully determined by the initial conditions of the universe.
