asymmetry
|
The notion that while X causes Y, Y does not cause X. It is established with temporal priority, manipulated events, and/or the independence of causes (see Brady (2011))
|
causal
|
In order to establish a causal relationship, the following criteria must be met concurrently:
-
Relevance of the variables within the broader theoretical and empirical context of the research
-
Clear Theoretical Framework
-
Clear conceptualization
-
Exclusion of alternative explanations
-
Asymmetry
-
Significant (and sufficiently strong) statistical association

symmetry
|
In the context of causation, symmetry is understood as the law-like regularity of events. There needs to be a recipe (causal mechanism) which regularly produces effects from causes (see Brady (2011))
