I had similar biases and wasn't able to make a decision because of it, so eventually went with one of the robo advisors (Vanguard) for those reasons. While I don't like not having more control, letting others make decisions has essentially taken my bad behavior out of the equation.

FWIW Vanguard has about 35% allocated to international for me, so it's surprising to see that Bogle wouldn't recommend international exposure.
