Treat as directional. Self-selection biases: forms split into multiple steps are likely to be longer, more complex, and configured by more sophisticated marketers — the lift may reflect form-author quality, not pagination per se.\n\n**Use carefully in Candid writing:** When citing, **disclose the source year (2014), the dataset (Formstack account-level, not controlled), and that the lift evaporates below ~7 fields** (see [[zuko-multi-step-only-helps-above-7-fields]]).
