John Carlos Baez thinks Sabine has a point.

>Despite the silly clickbait title of this video, Sabine says a lot of interesting stuff in it: her criticism of claimed deviations from Lorentz invariance in loop quantum gravity is about as good as you'll get from anyone who hasn't actually worked on loop quantum gravity. I worked on it for about 10 years, and the situation is even a bit worse than she makes it sound.

The fundamental reason for this is simple. Humans are prone to cognitive dissonance. Meaning, we do absurd things to avoid painful thoughts. And anything that questions our sense of identity, is a painful thought.

So if my self-image is, "I've advanced our understanding of the fundamental nature of reality," then the idea that my contributions weren't useful becomes painful. So we avoid thinking it, challenge people who question our past contributions, and so on.

The natural result of this cognitive dissonance is a feeling of undue certainty in our speculations. After all certainty is merely a belief that one idea is easy to believe and its opposites are hard to believe. We imagine that our certitudes are based on fact. But they more easily arise from cognitive biases.

And this is how a group of intelligent and usually rational people descend into theology whose internal contradictions can't be acknowledged.

I know people have strong reactions to her and her sensational style, but that is a serious recommendation from a knowledgeable person, so I think we can give this thread a second chance. (Someone emailed and asked us to.)

All: please let's keep the comments on topic and substantive (and avoid the sensationalism and personality aspects).

Edit: this subthread was getting too off-topic so I moved the replies to https://news.ycombinator.com/item?id=41814764. Feel free to reply there if you want.

If you want to reply to https://news.ycombinator.com/item?id=41811140 or say something Sabine-adjacent, please do it here. (This is so https://news.ycombinator.com/item?id=41808143 doesn't get too offtopic)

She was ripping on the valuations and economics of quantum computing companies the other week, and her critiques were such that they could be levelled against capitalism itself and basically any company in the market. Was an obvious and clear step way out of her area of expertise.

Perhaps he'll contribute to this thread (or perhaps it would waste his time)
