Q

What did Wakefield conclude?

A

That harmful dysfunction is the key notion - where dysfunctions refers to “failures of internal mechanisms to perform naturally selected functions”.
To conclude that a given behaviour is disordered “requires both a scientific judgement that there exists a failure of designed function and a value judgement that the design failure harms the individual”.
Therefore, unless there are dysfunctional consequences to the invidivdual, in that they are unable to perform a natural function, it makes little sense to call behaviour abnormal.
