Blackmore presents a lengthy description of some anomalies that she observed in Sargent's lab (she does cite and quote from the articles Miquel quoted) when she visited because of her own failures to obtain the Psi effects that Sargent was reporting. Essentially, there were some indications that someone might have been controlling which envelopes were being selected. There was a set of identified envelopes in a drawer. These were supposedly used just to replace envelopes selected from the target pile. The numbers of cards remaining in the drawer after several experiments were inconsistent with what they should have been. She also reports that they found various envelopes "hidden" around the room, which would have been necessary if substitution was going on. There was also a short comment on possible prompting of subjects by Sargent. She acknowledges that what she observed could not account for the degree of hits obtained. > >I will also admit > >to being influenced by an argument Blackmore attributes to Pierce > >(she discounts it herself) that it is easier to believe that > >cheating is going on than in true Psi effects, which are > >incompatible with so much of natural science.

Contrary to Miquel, I do not see the charge as a worse ethical violation than leaving Psi results to stand without including this hypothesis. Believing in such things has led to far greater harm to people than erroneous charges of scientific cheating. Moreover, it is relatively easy to rebut the charges if they are untrue. That in essence is what would normally happen by multiple researchers replicating an effect, unless one wants to get into conspiracy models of cheating. The possibility of cheating is increased, I think, whenever you have a lab or center that depends on the existence of some phenomenon for its own existence. There must be tremendous pressures to produce positive results, not only on the chief investigators, but also on all staff involved in a project.
