He doesn't listen to scientists. He is far more a fan of British bulldog Quasi-Churchillian Boris exceptionalism. The lockdowns so far have happened because he has been serially behind the curve at every juncture, making each wave much worse than it need have been. Didn't learn from what happened in Italy, preferring to cheerily tell us that we'd beat the virus in twelve weeks. Sent untested old people from hospital straight into care homes, killing thousands. Encouraged all sorts of shenanigans in the summer, eat out to bloody help out, didn't see the autumn wave coming until it was too late, and still didn't listen. You think he finished with making mistakes? I should bloody coco... Passports...Traffic lights...Here we go again...

Those scientists who he won't listen to have done all the good work for him. They're all in pharmaceutical companies. He just wears a white coat and a silly hat.
