Focusing on the success of others can make us selfish

Credit: public domain picturesIt is believed that the success of humans as a species depends to a large extent on our ability to cooperate in groups. Much more so than any other ape (or mammal for that matter), people are able to work together and coordinate their actions to produce mutual benefits. But what do we base our decisions on when we know whatever we do will affect those around us?

New research involving Dr Lucas Molleman, an expert in decision making and human cooperationin the School of Economics at The University of Nottingham, suggests that successful cooperation in groups depends on how people gather information about their peers, and how they base their cooperative decisions on it. The broader implication of this research is that the type of information we use to make our decisions can affect our social decision making.

The research, conducted at the University of Groningen in The Netherlands, is published today, Monday February 16 2015, in the academic journalProceedings of the National Academy of Sciences of the United States of America (PNAS).

Cooperation is of interest to both the natural and social sciences. Biologists wonder how cooperation could have evolved by natural selection: it is puzzling how cooperation can be beneficial when it is possible to behave selfishly and take advantage of the cooperative efforts of your group. Psychologists and economists try to understand why many people are willing to sacrifice their own welfare to benefit their social environment.

Understanding the decision making process

Dr Molleman, from the Centre for Decision Research and Experimental Economics, said: "The question that our research tries to answer is: 'How do people make decisions when their actions can affect the welfare of others?' More specifically, we want to know how people determine their behaviour when they have to cooperate in groups."

In these situations, a beneficial outcome for the whole group can be achieved if everyone works together. Individually, however, people might be better off by making selfish choices. Because of the possibility of others taking a free ride, people pay close attention their fellow group mates when they make decisions. For instance, they cooperate if others also cooperate, but act selfishly when others do not cooperate.

Who is selfish and who isn't?

Two hundred participants were invited to a computer lab at the University of Groningen. They were asked to make decisions that affected their earnings. Groups were formed in which the participants could choose between a selfish option (increasing their own earnings) and an option that benefitted all members of their group. In between making their decisions, people could gather information about their fellow group members; about the choices of the majority and information about which option paid off best.

Dr Pieter Van Den Berg from the University of Groningen said: "From previous research we know that people differ quite strongly in what kind of information they are interested in: some people are 'majority-oriented' and tend to look at the behaviour of the majority in their group, whereas others are 'success-oriented' and try to find out what kind of behaviour pays off best. In this experiment we studied how these different types of people behave when they have to cooperate in groups."

Dr Molleman said: "It turns out that behaviour in groups of success-oriented people was much more selfish than groups of majority-oriented people. As a consequence, the people in the majority-oriented groups tended to earn more money in the experiment since they cooperated more.

Google brings Android One devices to Philippines

Google brings Android One devices to Philippines

17 February, 2015

Google has launched Android One devices in Philippines. The two phones - the Cherry One and MyPhone Uno - will go on sale in the coming weeks on Cherry Mobile and MyPhone networks, respectively.

Both phones are similar to the Android One devices sold elsewhere but have a newer version of software. While those in India, for example, are still stuck on Android 4.4.4 KitKat, the ones being launched in Philippines are running Android 5.1 Lollipop, similar to the ones launched in Indonesia recently.

Philippines is the sixth country to get Android One, and Google will be bringing it to more countries in the future. Hopefully, that Android 5.1 update is also seeded to other devices soon.

Google’s Next Bid to Lower Mobile Data Costs: Zero Rating

Global Web companies like Google and Facebook know that most of their future growth will need to come from emerging markets. But as smartphones continue to bring more people online, data-plan costs and other hurdles are preventing those people from using mobile Web services.

In response, Google engineers in recent months have talked to select app developers in emerging markets like India about the company’s plan to reduce or eliminate the mobile-phone data costs that people pay to use apps on Android-powered devices, a practice known as “zero rating,” according to one person involved in the talks and two people briefed about them.

Zero rating has been around for years but typically comes in the form of one-off deals between a wireless carrier and an individual app developer like Facebook and WhatsApp. It is then promoted by both parties to their customers. The Google effort aims to be much broader, potentially allowing any developer to zero-rate the mobile data used by their app
