Scott explores why journalists struggle to write controversial articles about topics like COVID-19 due to experts' reluctance to be interviewed. Longer summary

Scott discusses the challenges journalists face when writing articles about controversial topics like COVID-19. He explains that experts are often hesitant to give interviews for fear of being misquoted or having their nuanced opinions stripped of context. This leads to a situation where it's easier to produce 'illegible knowledge' (like experts posting opinions on Twitter) than 'legible knowledge' (like well-sourced newspaper articles).
