On perfectionism, sometimes being accurate comes under the heading of 'harm no-one'. It's very much a reason why I end up longwinded on SR and at work.
I have no clue how to reason myself out of it - I see results from sloppiness or carelessness that impact on lives. Something said on a forum as scientific fact which causes fear and hopelessness but which was never fact. A policy created in response to badly read legislation which de-humanises kids to prevent prosecution which has never taken place, which exists only as a fearful prospect in the mind of the careless reader.
I know I will make mistakes, but I have no idea how to stop striving for accuracy.
