Whether you like it or not has no bearing on whether it's true. In fact that's a confirmation bias right there. Presented with evidence of something you find unpalatable you simply reject it outright purely on the basis you don't like it. Personally I'd rather know.
The point isn't that evidence has no power, it's that it has dramatically less power than most people think. However there are strategies for getting us out of the personal bias quagmire, such as the scientific method and the approach described in the article of providing an account or explanation of your position and the reasons for it. The debating rule of first explaining your opponent's position in your own words, but in a form they accept as being accurate, before trying to rebut it is also hugely powerful. These do seem to work and help lead us to better outcomes, so this is valuable and actually useful work.
