This episode of Crash Course Philosophy talks about William James. He's a little more than halfway through the video.
It's neat because it talks about William James' conditions for belief without evidence. He still thought that if evidence exists, you should look for it. That seems to refute Russell's Columbus example. There is evidence Columbus sailed in 1492, so I feel like James would still think believing otherwise would be irresponsible.
The philosopher discussed first in the video, W. K. Clifford, says there is no such thing as a private belief. We all affect one another with our words, with our actions. It's scary, but neat.
