How can both studies be correct?

Confirmation bias: the answer depends on the assumptions that analysts if the evidence held before they started the study. It's the opposite of true science, which is indifferent about whether the initial hypothesis is upheld or undermine by the inevitable conclusion a true view of the evidence leads to.

Have you ever noticed that the same people always come up with a whole row of similar-sounding answers? Or, worse, that they don't apologise when it is pointed out they made a mistake?
