It's interesting to think how the terms "complexity", "bias", and "variance" could also apply to people's beliefs. You could make an analogy that less sophisticated thinkers (low complexity) are highly biased and don't sufficiently adapt their beliefs (low variance) depending on the situation (data).
But interestingly, as the xkcd comic demonstrates, it's also common for people to over-generalize (overfit) based one or two instances of experience (few data points). We tend to call these people "biased" because they often seem to have prejudices that don't fit all the data that's actually out there. But from their point of view, with limited experience/data, they actually are fitting perfectly and would consider themselves "unbiased". So "bias" is a matter of perspective (a matter of which dataset you have).
