How to allocate impact shares of a past project

This post is inspired by question 1 (source).

A participant’s share of impact on a project is the product of the percentage contributions of the project’s influence line (motivational and additive impact considered separately). Combining multiple entities’ estimates can increase shares’ allocation accuracy.

C1-1 inspires 20% of B1’s action. This action motivates A’s project by 5%. Thus, C1-1’s impact share on A’s project is 20%×5%=1%.

The % share of contributions of all considered influencers does not need to total 100%, since some may be unspecified and actions may be taken by free will. The % share of any influence line segment is the extent to which the nodal entity made it so that the next participant took the step with further impact. These shares should be estimated by multiple individuals in order to increase accuracy. Influence nodes can be any physical and juridical persons and other entities or their groups and networks.

Influence can be both positive and negative, but negative-value certificates would likely be rejected by participants. Negative influence can increase the need for positive influence and so increase the value of other nodes’ contributions. A positive influence can be mistaken for a negative one if a negatively interpreted action, such as a false post, inspires a positive action, such as writing an accurate post. Counterfactual impact should always be considered.

The quality of actions and projects, in addition to their existence, can be influenced. This should be accounted for separately, since the percentage calculations differ. For example, if B1 improves A’s project by 5% (but does not motivate it), B1’s (additive) share of impact is 100%/​105×5=4.76%. Total impact is the sum of motivational and additive impact of all influence lines from the considered node to the project.
