I have exactly one paper that uses “unique”, and every use is in the mathematical sense.
Probably I overuse semicolons.

This is the main graph from Oprea (2024), showing that the fourfold pattern arises in lotteries (grey) and in mirrors (white).
And that same graph from the replication study, showing that the effect arises in lotteries, _but_not_ in mirrors.

💡 Open science: A team of researchers at Shandong University has attempted to replicate Oprea (2024 AER). The results do not replicate.
Oprea 2024 reported an online lab experiment, and found that prospect theory anomalies occur not only for lotteries, but also for deterministic 'mirrors'.

Even more troubling: Oprea (2024) is not only online subjects. It has an in-person student sample with much higher stakes. And if we restrict attention to the student sample then the result also vanishes.

If we restrict attention to subjects who passed comprehension checks, then the main result vanishes. Anomalies arise for lotteries but not for mirrors!

But the new analysis convincingly shows that the result is driven by participants who failed comprehension checks.
Those who pass comprehension checks treat lotteries and mirrors very differently!
