- "a successful representative democracy isn't just about choosing the best person in each individual constituency, but about making sure the resulting legislative body actually comes close to reflecting the makeup of the Canadian population."
- "a group of white men aren't going to be able to make adequate laws for a diverse population of women and minorities because they won't be able to wrap their minds around everybody's issues."
- (2) is true because "we all have biases we don't even know we have, and ... these biases affect the decisions we make, no matter how well-meaning we are."
- Therefore, Parliament should have more minority MPs.
It is certainly true that "we all have biases we don't even know we have, and these biases affect the decision we make, no matter how well-meaning we are." Cogsci has been riding that horse for years (although Kant got there first). But (2) doesn't follow from (3). (3) says that we have biases; (2) however goes further and says that these biases cannot be overcome. And it's the claim that the biases cannot be overcome that needs to be established -- I've never seen an argument for that which actually works.
Here's a possible argument (that doesn't work) to show the problem:
- We have biases naturally occurring as part of our mental make-up.
- Anything that occurs naturally (either inborn or developed) cannot be overcome.
- Therefore, these biases that are part of our mental make-up cannot be overcome.
