Anchoring bias centers on the way the first piece of information acts as a reference point for all later judgments. When you encounter a first thought or initial number, your subsequent decisions tend to orbit around that anchor, with only minimal adjustment as new information comes in. The phrasing “sinking to first thought” captures that tendency to cling to that initial idea as the baseline for reasoning, rather than thoroughly evaluating all possibilities or recalibrating with new data.

In practice, this shows up when people fixate on an initial price or estimate and find it hard to move far from it, even when better or more relevant information becomes available. That’s why the other options don’t fit as well: evaluating all possibilities implies broad, unbiased consideration rather than clinging to the first cue; overgeneralization means applying a rule too broadly, not anchored judgment; and confirmation bias involves seeking information that confirms a preconception rather than being anchored to an initial reference point.
