This is very relatable. Everything is permanently recorded here and I have a big fear of being seen as stupid. Sometimes my high IQ spits out some very inane commentary. I never like passing inaccurate information. I often hedge my bets and say equivocal opinions when I'm uncertain even when I'm feeling convinced about something on a gut level.  I've been wrong about so many things even when I'm directionally correct. It's often a challenge to speak my truth. Eyeballs everywhere get to judge my two sats of input. Can anyone else relate to that? 

 That's called self censorship  

 Very true. 

 That's one term that applies. Another term to consider is "discernment" or perhaps "discretion"? Have you ever been gunned down because you shot from the hip? I have. 

 I feel that way, often misunderstood. Perhaps I’ll learn to make memes.
