Here's the conclusion:
The history of the stem-cell debate is a study of what happens when politics and science reach out to each other. The politicians were guilty, but the scientists were more guilty, for they allowed no, they encouraged—politicians to make stem-cell research a tool in the public fights over abortion, public religion, and high finance.Read the whole thing.
In the small demagogueries of a political season, the science of stem-cell research became susceptible to the easy lie and the useful exaggeration. A little shading of truth, a little twisting of facts yes, the politics corrupted the science, but the scientists willingly aided the corruption. And with this history in mind, who will believe America’s scientists the next time they tell us something that bears on an election? We have learned something over these years: When science looks like politics, that’s because it is.
