Fauci told the American public that masks don't work. My mom already owned N95 masks and got looked at like a crazy person because she was wearing one when shopping, ect. Then suddenly it became "the science" on the heels of all the research that already existed... Turns out it was a noble lie to protect the supply of masks while production caught up with demand.

It looks like Fauci lied about the lab leak theory for his own reasons, although I'm pretty out of date on that issue. Even if not Fauci we know that scientists with conflicts of interest all signed an open letter saying the theory is bunk and it was uncritically paraded around as "the science."

We were very clearly told "get the vaccine and you'll get your life back" but that hasn't even happened in paces like Israel with extremely high rates.

The vaccine was initially sold to us as something that would prevent infection, but that turned out not to be true. (I'm willing to concede this probably wasn't a lie but just something we learned as time went on, but it does reflect that they may have been overconfident and refrained from discretion because it was a pro-vaccine talking point)

Vaccine passports used to be conspiracies. Same with the idea that we'd have to get booster shots every so often to stay current.

And this is probably the biggest one: So many of the politicians pushing covid restrictions fail to practice what they preach outside of photo ops. The list is a mile long of local, state and federal politicians constantly violating their own restrictions. It lends credibility to the idea that none of them believe any of it.
