Why you can't teach human values to artificial intelligence.

However, the project to merge social science and artificial intelligence ran into more than a few bumps in the road. In a 1990 book, sociologist Harry Collins suggests why. Collins argued that every community "knows" certain tacit things that are difficult if not impossible to fully represent computationally. Or, in other words, "computers can act intelligently to the degree that humans act mechanically." Lots of human activities (like voting, greeting, praying, shopping, or writing a love letter) are "polymorphic"--socially shaped based on an understanding of how society expects the action to be performed.
