The IKEA Effect: A Conceptual Replication
Research-assisted source review
- What it supports
- The replication supported higher willingness to pay after self-assembly and evidence consistent with psychological ownership, while some boundary findings differed from the original.
- Where it may not transfer
- A conceptual rather than exact replication, with a limited product task and sample. Mediation evidence does not prove one exclusive mechanism or justify adding labour.
