Brandolini's law (or the bullshit asymmetry principle) is an Internet adage coined in 2013 by Italian programmer Alberto Brandolini. It compares the considerable effort of debunking misinformation to the relative ease of creating it in the first place. The adage states:

The amount of energy needed to refute bullshit is an order of magnitude bigger than that needed to produce it.

The challenge of refuting bullshit does not come just from its time-consuming nature, but also from the challenge of defying and confronting one's community.
