In one study, diffusion of responsibility does not occur if another bystander is perceived as being unable to help. [28] Group psychology can also influence behaviour positively; in the event that one bystander takes responsibility for the situation and takes specific action, other bystanders are more likely to follow course.
Example of six evidence accumulation sequences from an unbiased (100% noise) source. The dotted lines indicate the thresholds for decision making for each of the two alternatives. The drift-diffusion model (DDM) is a well defined [19] model, that is proposed to implement an optimal decision policy for 2AFC. [20]
Expansion diffusion: an innovation or idea that develops in a source area and remains strong there, while also spreading outward to other areas. This can include hierarchical, stimulus, and contagious diffusion. Relocation diffusion: an idea or innovation that migrates into new areas, leaving behind its origin or source of the cultural trait.
A social experiment is a method of psychological or sociological research that observes people's reactions to certain situations or events. The experiment depends on a particular social approach where the main source of information is the participants' point of view and knowledge.
Diffusion is a stochastic process due to the inherent randomness of the diffusing entity and can be used to model many real-life stochastic scenarios. Therefore, diffusion and the corresponding mathematical models are used in several fields beyond physics, such as statistics , probability theory , information theory , neural networks , finance ...

For example, when one life is at risk, the value is $100; when ten lives are at risk, the value decreases to $80; and when fifty lives are at risk, the value decreases to $50. Compassion fade explains this as people's perception that, as the number of lives in need of aid increases, individuality decreases and thus the value of the life decreases.
