The original argument correctly characterized Bakshy et al. as showing that algorithmic effects exist beyond homophily, not that they exceed homophily effects.

[DEFENSE-REBUT → v8cm4r] The original premise [1] stated that 'the algorithm contributed an independent additional reduction in cross-cutting exposure beyond homophily' which accurately reflects Bakshy et al.'s finding that both factors contribute. Establishing that algorithmic effects exist beyond homophily is sufficient to support the sub-claim that algorithmic effects are not fully explained by user self-selection. Therefore, The original argument correctly characterized Bakshy et al. as showing that algorithmic effects exist beyond homophily, not that they exceed homophily effects. (Warrant: When an argument claims that a factor contributes effects beyond a baseline, citing evidence that both the factor and the baseline contribute independently is accurate characterization, not misrepresentation.)

These are challenges this argument’s reasoning pattern must still withstand. Answering them on Isonomia strengthens the argument.

• Are there other events or causes that could account for the presence of the sign?Open
• What is the strength of the correlation between the sign and the event/state it is taken to indicate?Open
• Has the sign actually been observed reliably in this case?Open

No one has cited this argument yet.

No arguments cite this one yet — no one has built on or contested it. That is an absence of engagement, not a finding of soundness. Build on or contest it on Isonomia to change that.
