Examples:

1) Not testing for COVID in places that didn’t previously have known cases of COVID.

2) Treating COVID like flu until hospitals are overwhelmed.

3) Believing in herd immunity until "second waves” after opening up.

4) Not using masks until proven that they work to prevent transmission.

5) Not protecting from aerosol transmission until proven that there is transmission.

6) Not believing in strong lockdowns, until countries that adopted them are enjoying normalcy while others are in perpetual soft lockdowns

7) Believing lockdowns rather than the virus cause economic harm, until lockdowns are needed everywhere the virus is allowed to spread.
