- Hong, Witt, and Szafir further show a weighted average illusion: larger or darker marks can pull viewers' estimates of the mean \(x\) and \(y\) position toward visually salient points even when size is not meant to weight those means.

Verification¶
Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.
Does it back the claim? Not recorded. The single citation of this work carries no recorded support check.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
