The Three Faces of Overconfidence
Research-assisted source review
- What it supports
- The three forms arise under different conditions and can have different consequences; treating them as interchangeable or assuming a shared psychological origin is a conceptual error.
- Where it may not transfer
- This is a narrative review, not a meta-analysis producing one effect estimate. Its main value is taxonomy: product claims still require a direct measure and an appropriate outcome or comparison benchmark.
