The Most Common Trap: "Can't Tell" vs "True"

The single most common error in UCAT Verbal Reasoning is selecting "True" when the correct answer is "Can't Tell." This happens because the statement seems obviously correct — either because it is true in real life, because it is very plausible given the passage, or because it is a tempting inference. This lesson focuses entirely on this specific error, with extensive practice to recalibrate your judgement.

Why This Error Is So Common

Reason	How It Leads to Error
Prior knowledge	You know the statement is true in the real world, so you assume the passage supports it
Plausible inference	The statement seems to follow logically, but it actually requires an extra assumption
Emotional agreement	You agree with the statement personally, which makes it "feel" true
Speed pressure	Under time pressure, you take shortcuts and skip the verification step
Confirmation bias	You look for evidence supporting the statement and overlook the absence of evidence
