This suggests that, at least in our experimental environment, generational reciprocity alone could boost future-oriented investments, without complex monitoring or detailed historical transparency.

Thus, even the expectation that future generations might reciprocate—without direct observation of your own generosity—motivates investing forward.

Remarkably, observing past actions doesn't matter. Players contribute more to future generations simply when the next generation can potentially give back—even if past generosity is hidden.

To examine this, we randomly vary the info sets:
Some see nothing about previous players.
Some see past investments forward.
Some see how much was passed back and forward.
There are other treatments described in the paper and appendix.

We vary treatments by changing the ability of future players to give back and the information available about what others did. Theory predicts a clear link: knowing past generosity should incentivize giving forward.

Each player represents a "generation" and decides how much of their resources to pass forward to the next player and—crucially—how much to pass backward to the previous one.

In short, cultured meat may have large direct effects on animals, but in our experiment, it does not prompt a social turn against animal agriculture.

The backlash effect even extends to a stronger preference for meat relative to plant-based meat when people are exposed to cultured meat.

The backlash effect even extends to a stronger preference for meat relative to plant-based meat when people are exposed to cultured meat.
These attitudes depend a lot on the social environment-exposure to strongly negative attitudes toward cultured meat can enhance this effect (while some positive messages we study do not succeed in counteracting this).

Why? It looks like people react to a fear of cultured meat—perhaps thinking it will replace animal-based meat—by expressing protest views in a backlash or, in psych, "reactance" effect.

@zdgroff.bsky.social, Bobbie Macdonald and I consider the impacts of a different new technology: "cultured" meat, i.e., meat that is grown in a lab from cells. 3/
