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.
