The official monthly publication of The British Psychological Society is The Psychologist.
The Psychologist has published a letter signed by a groups of psychologists who challenge the affirm-by-default approach required by British Psychological Society. The letter goes as far to question evidence for this approach.

The letter can be read in it’s entirety on the website of the journal.
