A study that used the field setting you describe is done by Bateson et al. (2006).
As for the mechanism, they write:
we believe that images of eyes motivate cooperative behaviour because they induce a perception in participants of being watched. Although participants were not actually observed in either of our experimental conditions, the human ...
The short answer is that anyone who gives you a short answer should be treated with suspicion. ;-p
The StackExchange was founded in 2008, and has seen a lot of changes since that time. That has provided the science community with little time to study the phenomenon in much detail. As such, there are many many theories, but little consensus, and no ...
When people ask others whom they have a relationship with to sponsor their activities for charity, the requester is providing two things to the potential donor:
An awareness of the cause and the given charity which supports that cause (the cause is, in essence, a problem)
An prepackaged opportunity to help the person they know contribute to the cause (a ...
In addition to purely altruistic motivs for volunteering, there is some evidence it can occur for very different, more selfish reasons. Clary et al. (1998) developed a functionalist theory of volunteering and identified six different motives:
expression of humanitarian values
Your example of no student willing to object until one objects is analagous to Asch's conformity experiments. To quote the Wikipedia article:
In a control group, with no pressure to conform to an erroneous view,
only one participant out of 35 ever gave an incorrect answer. Solomon
Asch hypothesized that the majority of participants would not conform
The Stack Exchange model is based on gamification. Gamified environments typically deploy incremental rewards that tap into the brain's reward system, making these applications addictive, in a quite literal sense. In addition, reputation increases come with incremental gain of moderator abilities, which give a sense of power.
This is an interesting question as it has been of the opinion of many people around me that people who drive certain cars or are in a particular job or social status are selfish and don't care about anyone but themselves and maybe a little about those in their own circle of people. But is this true?
TLDR - It seems to be true from studies presented, ...
One related term I found is the bandwagon effect.
In layman’s term the bandwagon effect refers to people doing certain
things because other people are doing them, regardless of their own
beliefs, which they may ignore or override.
The general rule is that conduct or beliefs spread among people, as
fads and trends clearly do, with "the ...
One element of sponsorship-based charity is that it typically relies on existing social networks to generate donations. Thus, the participant is typically a friend, work colleague, family member, or fellow community member of the donor.
This will add a wide range of social processes to increase the likelihood of donation:
At a basic information-processing ...
This article might be helpful. In particular, humans need social connections (according to Maslow's hierarchy of needs). Stress initiates people to come together. It was thought that women would come together during disaster and men would fight (i.e. the fight and flight response). However men also come together during disaster.
A distinction must be made ...
This should be a comment, not an answer. But because of the formatting I put it here.
My speculation: gamification/social acceptance + altruism + curiosity + flow.
Gamification/social acceptance: you need to prove to folks in this site that you do know stuffs
Altruism: you once had this question before, so you can related this to yourself. Or you know ...
You are confusing belief or faith with a hypothesis.
Instead of a methodological answer, this question might, perhaps arguably, be tackled better from a slightly more philosophical angle. Let's go through the relevant terminologies.
An acceptance that something exists or is true, especially one without
I spent over 5 weeks hanging out with homeless people in Kalamazoo, MI by a nearby homeless shelter. I engaged with them nearly every minute of free time I had after work and on weekends. What I observed regarding food was actually an abundance. When someone releases a study indicating that someone doesn't get "enough" to eat, that is extremely subjective. I ...
