> Would the symmetrical statement, that you can only meaningfully agree with an expert if you are humble and have done your homework, be true? Yes. But agreeing or disagreeing is not the only option. In [1] the authors suggest that the crustal anisotropy is decoupled from horizontal basal tractions and, instead, created by upper mantle vertical loading, which generates pressure gradients that drive channelized flow in the mid-lower crust. Do you agree or disagree? The truth is, you probably don't have a position on the issue. If pressed, you might defer to the expert opinion that crustal anisotropy is created by upper mantle vertical loading. But that's not the same as agreeing with it. It's just saying "I don't know, but here's what somebody else says". Of course, agree/disagree/defer is still too rigid: you can humbly tend to agree (based on some homework) while mostly deferring, etc. [1] https://advances.sciencemag.org/content/6/28/eabb0476 https://advances.sciencemag.org/content/6/28/eabb0476
