I recommend you sit back and review how you arrived at this conclusion. I have personally never interacted with Elizabeth Holmes and everything I know about this person has come through the lens of first media, then courts, and then media again.
It is the media, including the New York Times, that is creating this impression, is that not the case?
So, correctly your sentence would read “still has the ability to fool the handful of people who interact with her directly and then share accounts with us”.
So now, having established the actual state of affair in this ‘information graph’, the next question naturally is: “are these people really fooled or are they fooling me?” I.e. Do we have gullible people in positions that require inquisitive and thorough mindsets, or, even more “actors” pretending to being journalists, a sort of “dissociative [professional] identity disorder”.
