Ask HN: Could we train a computer to detect lies?
I was reading the Fake Amazon Ambassador Twitter thread (https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=26636021) and there was a discussion about how detecting liars has been an unsolved problem for thousands of years.<p>It got me thinking. Couldn&#x27;t we just build a giant dataset of people telling verified lies and use it to train a model to detect liars?<p>Ultimately, if humans give outward signs when they lie, I expect that a computer should be able to detect them.<p>Anyone ever tried this?
