Step 1: Concept Identification:
The query defines a cognitive bias characterized by the post-event belief of having anticipated the outcome, as if it were predictable.
Step 2: Analysis of Options:
(A) Misinformation effect: This involves memory distortion by post-event information, distinct from perceived predictability.
(B) Constructive processing: This memory theory posits that memories are rebuilt during retrieval, which can lead to biases like hindsight bias.
(C) Hindsight bias: This directly describes the "I-knew-it-all-along" phenomenon, where past events appear more predictable in retrospect. This aligns perfectly with the question's premise.
(D) Recency effect: This refers to the enhanced recall of recently presented information, unrelated to retrospective predictability.
Step 3: Conclusion:
The phenomenon of falsely believing one could have predicted an outcome after its occurrence is termed hindsight bias.
