For example:
> "Chemical imbalance. Thanks in part to the success of direct-to-consumer marketing campaigns by drug companies, the notion that major depression and allied disorders are caused by a 'chemical imbalance' of neurotransmitters, such as serotonin and norepinephrine, has become a virtual truism in the eyes of the public... There is no known 'optimal' level of neurotransmitters in the brain, so it is unclear what would constitute an 'imbalance.' Nor is there evidence for an optimal ratio among different neurotransmitter levels."
They also discourage the use of the term 'brainwashing' (introduced in the 1950s during the Korean War by the US government), although I'd argue that 'operant conditioning' is an acceptable and well-researched concept, particularly when it is applied steadily from a young age through to adulthood:
