Agreed. It is simply unfortunate that the scientific investigation of anomalous terrestrial and intrasolar phenomena must, at this time, occur in a social context of superstition, scientific illiteracy, and a mindless will-to-believe associated with the decline of theological credibility. The problem, it seems to me, is not the absence of an appropriate experimental methodology, but how to isolate it from mass ignorance.

Again, I agree that optical and radio scans must be considered only a temporary expedient (with the possible exception of the placement of detection devices on the dark side of the moon). Dr. Tough, in fact, isn't entirely convinced of the ultimate effectiveness of RA SETI or OSETI.

Not a good bet, but what other technological alternative to we have at this time, assuming that we did not choose to search, rather the search chose us. The motivating curiosity is not going to go away, and never has, despite the lack of positive reinforcement.
