Can you remember the last time you realized you were wrong, and had to change your mind? If not, you are probably not a critical thinker.

For a scientist like myself, all knowledge ids provisional and changing your mind is essential to the process.


Retired scientist and environmental lab manager. Lifelong critical thinker who just started attending Socrates Cafe and Nietzsche in Depth meetups.
