Stephen Harper government confuses science for mere opinion

Yes. Yes they do. Or, like many many ppl (including scientists) they prefer their own opinions to science that refutes said opinion. We demand better of our decision makers though.

The common law is clear about this. In court, opinion evidence is generally inadmissible. Why? Because the law has legitimate concerns about the relevance or reliability (or both) of opinion evidence, and its potential to mislead judges and juries.

But expert scientific opinion — the kind Harper and Oliver apparently believe we should listen to — is admissible. Why? Because, subject to tests of relevance and reliability, such evidence often proves invaluable in assisting judges and juries in reaching informed decisions.
