The presumption of incompetence
The 'presumption of incompetence' refers to the widespread and ingrained belief
that the innate limitations of people with an intellectual disability make them
unfitted for parenthood. Such a starting point leads inevitably to the view that
any parenting deficiencies are part of their nature and therefore cannot be corrected.
The presumption of incompetence draws people into expecting parenting failure
and then only seeing the evidence that supports this preconception. This outlook
brings particular dangers in the context of the working of The Children Act 1989
where decisions may be made on the basis of prospective findings (ie. on the likelihood
of parents harming their children) judged on the 'balance of probabilities'.
