Three sessions on how a feed decides what your student sees.
Ranking systems are not conspiracies; they are signals, weighted. Your student learns what actually gets measured, why content producing a strong feeling spreads faster than calm content, and what follows from optimising for attention.
The third session is what makes this unit unusual: a great deal of what gets said about “the algorithm” is overstated or invented, and the unit sorts well-supported claims from the rest. It does not argue that algorithms are harmless, and it does not endorse every dramatic claim about them either.
Teaching a student to ask what the evidence supports outlasts teaching them a conclusion.
