You're confusing strong evidence for causality with establishment and absolute proof of causality. This is even discussed in the sources you've cited (second link). For example here is a quote from one of your sources about the necessity understanding the underlying mechanism before causality can be established:

> A causal mechanism is the process that creates the connection between the variation in an independent variable and the variation in the dependent variable that it is hypothesized to cause (Cook & Campbell, 1979:35; Marini & Singer, 1988). Many social scientists (and scientists in other fields) argue that no causal explanation is adequate until a mechanism is identified.

>If you argue this further I'm just going to conclude you're trolling and won't respond again.

>You are wrong. Face it.

Thank you for demonstrating your willingness to engage with opposing viewpoints even when supporting evidence is presented (;
