Interpreting Causal Arrows

From a channel Lumen includes in full: HHMI BioInteractive produces classroom science films for high school and college educators. Every sampled transcript teaches substantive biology: glycolysis enzyme steps, immunotherapy, polygenic inheritance, experimental design, and the evidence behind the K-Pg extinction. The titles are descriptive. Playful ones such as 'You Have Reptile Bones in Your Ears!' and the 'Estalló el Secreto' pun state their topic plainly rather than hiding it as a hook, so they are not clickbait. Only non-content uploads like trailers or webinars need to be filtered out by title pattern.
