Learning Quote by Lee Ross
““The channel factor principle, thus, is one key to understanding why some situational factors have bigger effects than might be anticipated and why some have smaller effects. Seemingly big interventions and campaigns that provide no effective input channel in the form of situational pressures, or no effective behavioral outlet channel in the form of clear intentions or plans, will generally produce disappointingly small effects. And seemingly small situational factors that operate on important input or output channels will often exert gratifyingly large effects.””

The principle explains that the impact of situational factors depends on whether they affect key input or output channels; small factors on crucial channels can have large effects, while large interventions lacking channel relevance have little impact.
In simple terms: Effectiveness of influences hinges on targeting the right pathways; big efforts fail without proper channels.
