Crowdsourcing truth at scale is the core of the current AI paradigm. But as these AIs get better at producing correct-looking outputs on tasks we don't fully understand, this paradigm is running into limitations. I believe the solution is to design truth-finding processes for and with AIs.
To build a mental picture of what that looks like, I find it useful to think about AlphaGo's move 37. Many Go players initially dismissed it as a bug, but its value became apparent as the game unfolded. In other words, even domain experts initially misjudged the AI, but the interactive process of Lee Sedol playing out the rest of the game lead to a more precise evaluation.
My high-level goal is to improve human supervision of non-human processes with new theories, algorithms, data collection schemes, and UIs. I'm always thinking about the following questions:
Does the model know something that I don't?
How can I ask the right questions to elicit that knowledge?
