People with fewer resources contribute more to actions against climate change. This is the main result of an investigation that, through a citizen science experiment, proposes to act collectively against global warming. The study, which has measured how a group of people acts in the face of common harm, has shown that people are willing to contribute more or less money to combat climate change according to their purchasing power. The research, published in the journal Plos One, has been carried out by researchers from the Rovira i Virgili University, the University of Barcelona, the University of Zaragoza and the Carlos III University of Madrid (Spain).
To achieve this, the researchers designed a citizen science experiment involving more than 320 people divided into 54 groups of six. The operation was as follows: distributed 240 euros to each group, whose members did not know or could relate to each other. Each member of the group was given a specific amount of money. In half of the groups, all had the same capital: 40 euros each. In the other half, the money was distributed unequally: from 20 to 60 euros to each member The experiment was carried out in the street and during the DAU table games festival organized by the Institute of Culture of Barcelona.
From here, each person had to contribute money to a common boat with the challenge of achieving, after ten rounds, a total of 120 euros dedicated to an action against climate change; in particular, plant trees in the Collserola mountain range (in Barcelona). With the money they had left, they obtained purchase vouchers. At the beginning of the experiment, everyone knew how much money each one had and in each round they could know how much each participant had contributed.

In this way, the economic effort that each one is willing to make for a collective benefit, in this case related to climate change, was put to the test. The results showed that, although all the groups achieved the collective goal of reaching 120 euros, "the distribution of the effort was very unequal," explains Jordi Duch, researcher at the Alephsys research group - Algorithms Embedded in Physical Systems - from the Rovira i Virgili University.
Specifically, participants with fewer resources contributed significantly more to the public good than the richest, sometimes up to twice as many. The researchers concluded that the poorest were part of the "generous groups", while the richest were classified in an "aggressive group".
The results suggest that future policies would benefit both from reinforcing climate justice actions and from educating in equity, instead of focusing on the understanding of generic or global climatic consequences, since this awareness has not been shown to generate equitable contributions.
"In fact, the study demonstrates once again that cooperation is better than competition when it comes to achieving socially desirable goals, and that in the case of climate change, cooperation between all the agents involved is necessary," says another. the authors of the study, Anxo Sánchez, professor of the Mathematics Department of the Carlos III University of Madrid (UC3M).
The analysis of the results indicates that in the groups in which there were no inequalities in capital, two behaviors could be differentiated: one that cooperates with amounts that would be considered fair (approximately half of their initial capital) and another part that cooperate much more than just. However, in the groups that started from the initial inequality, there are many more differences. Those who had more money (50 or 60 euros) contributed less than what is considered fair, unlike those who had less (20 or 30 euros) that proportionally contributed much more.
These results show that "given the inequalities, the poorest groups are more vulnerable and, therefore, those who suffer the most," explains Julián Vicens, currently a researcher at the OpenSystems group and a member of the Institute of Complex Systems at the UB. implemented in tablets, it simulates strategic social interactions based on game theory and poses social dilemmas that put individual and common interests in tension and machine learning mechanisms have been applied to identify patterns of behavior.
