💡 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'.

Research teams composed of pro-immigration researchers estimated more positive impacts of immigration on public support for social programs, while anti-immigration teams reported more negative estimates, from George J. Borjas and Nate Breznau https://www.nber.org/papers/w33274

Academics from poorer socio-economic backgrounds are more likely to
- not publish
- have outstanding publication records
- introduce more novel scientific concepts
- less likely to receive recognition, as measured by citations, Nobel Prize nominations, and awards.
