These human experiments have gone largely unchallenged and unquestioned by Congress, the medical profession, and the scientific community at large.

Every effort is made to control information. Secrecy is just one of the toggles on their control board. The mindset is in place, and they've done a lot of hiring over eight years, not just political appointees. And they've done a lot of firing or driving people out who might have countermanded or resisted. So, institutionally, it's not going to be simply a matter of flipping the switch to undo it. You're going have to bring in people dedicated to transparency, and you have to demonstrate that there are rewards for candor.

An attitudinal sea change. I think that's the hardest one to fix. Presidential directives, bills, provisions can all be rescinded, repealed, amended, but attitudes linger. The hardest thing is going to be to try to reverse an attitude, a bunker mentality that equates secrecy with either security or heightened efficiency and that regards transparency as an invitation to mischief and trespass. This default position of operating in the shadows is going to be somewhat appealing to whomever inherits office.

The real secrets start leaking out when there are too many secrets because people can't remember what's a real secret. There's a very famous line by National Security Advisor McGeorge Bundy: "If you guard your toothbrushes and your diamonds with equal zeal, you'll lose fewer toothbrushes and more diamonds." And that's where we are right now.

These human experiments have gone largely unchallenged and unquestioned by Congress, the medical profession, and the scientific community at large.

It will be important to restore those provisions, those disclose provisions, those release provisions so that presidents are indeed held accountable and their information and papers are made public.

I don't think that the problems or the issues relate to any single piece of legislation. I think that they really do relate to the mindset that after eight years is pretty deeply embedded. It is not going to be easy to reverse itself.
