If you haven’t seen any clear bias then you probably have a close enough outlook to them to not notice. And that’s fine, I don’t require everyone to have the same opinion as me for their comments to have value.

My impression of bias is probably born out of the leading polls that rightwing media and thinktanks in the UK commission them to do. You can fairly argue that these polls are externally commissioned so their tenor is a product of their issuer not yougov. But the overall impression I got was that they could be readily depended on to produce misleading propaganda against labour when it wasn’t being run by corporate technocrats.
