See, this is what blew me away when I read the book. I have worked in health research or research-related jobs my entire adult life. The idea that 100+ tests could be run from one drop of blood is like sci-fi talk. I know that SOMEDAY it could happen, but our technology is WAY away from this right now. Some of the knowledgeable folks in the book felt the same way and simply did not believe her. Others - KNOWLEDGEABLE people - were so fascinated by her that they believed her. I was shocked at how gullible some of these very intelligent people were. Only after the repeated issues and excuses did some of them finally see that she was a fraud.
She definitely has the knack for snowing people, you have to give her credit for that. But, yeah, psychopath.
