Tom Segalstad    Geology Professor
Most leading geologists, throughout the world, know that the IPCC's view of Earth processes are implausible if not impossible.

Marc Breedlove    Neuroscience Professor
I think most of the scientists working on these questions are convinced that the antecedents of sexual orientation in males are happening early in life, probably before birth whereas for females, some are probably born to become gay, but clearly some get there quite late in life.

Christopher Preston    Professor of Plant and Food Sciences
There are at least 42 publications extractable from the PubMed database that describe research reports of feeding studies of GM feed or food products derived from GM crops. The overwhelming majority of publications report that GM feed and food produced no significant differences in the test animals. The two studies reporting negative results were published in 1998 and 1999 and no confirmation of these effects have since been published.

Advocates of intelligent design argue that it is a scientific theory, and seek to fundamentally redefine science to accept supernatural explanations. The unequivocal consensus in the scientific community is that [evolution by natural selection is true and that] intelligent design is not science.

Rudolf Verspoor    Homeopathist
What emerges is a consensus that vaccination is not consistent with the principles of homeopathy, even if it is a crude application of the law of similars. Clinical evidence further suggests that vaccination holds serious short and long-term consequences both because of its effect upon the miasms, and because some constitutional types are particularly susceptible to vaccination shock.

Philip Morris    Tobacco Company
[There is] overwhelming medical and scientific consensus that cigarette smoking causes [diseases including lung cancer, emphysema and heart disease.]

Andrew Dessler    Climatology Professor
The small number of credible skeptics out there (e.g., Spencer, Lindzen) have spent much of the last decade searching for a negative feedback in our climate system. ... Most climate scientists, however, are reasonably certain that a negative feedback big enough to overwhelm the well-known positive feedbacks in the climate system [...] does not exist. ... it is extremely difficult to reconcile the existence of a big negative feedback with our past observations of climate variability.

Edward Prescott    Nobel Laureate in Economics
I don't know why Obama said all economists agree on [the need for a stimulus bill] - they don't. If you go down to the third-tier schools, yes, but they're not the people advancing the science.

Milton Friedman    Iconic Economist of 20th Century
Ever since Adam Smith there has been virtual unanimity among economists, whatever their ideological position on other issues, that international free trade is in the best interests of trading countries and of the world. ... [The] voice [of the consumer] is drowned out in the cacophony of the "interested sophistry of merchants and manufacturers" and their employees. The result is a serious distortion of the issue. ... "Protection" really means exploiting the consumer.

Huber Warner    Biochemistry Professor
Each one of the specific proposals that comprise the SENS agenda is ... exceptionally optimistic. Therefore, by multiplying the probabilities of success, the claim that all of these proposals can be accomplished, although presented with confidence [by de Grey], seems nonsensical. Consequently, the idea [we] will not only retard ageing, but also reverse it ... and do so within our lifetime, is so far from plausible that it commands no respect at all within the informed scientific community.

Al Gore    Environmentalist, Former U.S. Vice President
There are no longer any serious scientists producing peer reviewed scientific journal articles that [deny anthropogenic global warming]. The real scientific debate is over. The people who say global warming isn't real, they must get together on Saturday nights and party with the ones who think the moon landing was staged on a movie lot in Arizona.

Robin Hanson    Economics Professor
Regarding our best estimate of the employment effect of a small min wage rise, while many have recently said this is near zero, more say it is substantially negative, and I have asked around and found *no* economist who says that it is substantially positive. Thus, I conclude, any reasonable average of these estimates must be negative, and has been so for a while.
