The finding that algorithmic ranking produces different exposure patterns than chronological feeds does not license the inference that these exposure differences cause affective polarization.

[UNDERCUT] The 2023 Meta experiments found that replacing algorithmic with chronological feeds substantially changed exposure patterns but did not detectably change polarization. Exposure differences are intermediate outcomes; without demonstrated downstream effects on affective polarization, exposure changes do not establish polarization causation. Therefore, The finding that algorithmic ranking produces different exposure patterns than chronological feeds does not license the inference that these exposure differences cause affective polarization. (Warrant: Demonstrating that algorithms affect exposure beyond homophily does not establish that these exposure effects cause polarization when direct tests of the polarization outcome find null effects.)

• The 2023 Meta experiments found that replacing algorithmic with chronological feeds substantially changed exposure patterns but did not detectably change polarization.
• Exposure differences are intermediate outcomes; without demonstrated downstream effects on affective polarization, exposure changes do not establish polarization causation.

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

• Is the literature really agreed that defects of kind K bias inferences in direction B, or is the bias direction itself contested?Open
• Does study S actually have defect D, or is the description of S inaccurate?Open
• Is the expected magnitude of the bias from D large enough to overturn S's reported effect, or is the effect robust to plausible bias corrections?Open
• Has S (or a follow-up study) performed a robustness check or sensitivity analysis that addresses defect D directly?Open
• Is this critique applied consistently — i.e., would it apply to studies on the other side of the debate that share the same defect kind K?Open
• Is H supported by independent studies that do not share defect D, such that S's defect does not undermine H itself?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.
