Simpson's Paradox : Foundational Inconsistency/Incompleteness of Not only Statistics but also Causality in Universe : Evolution of Human Logic Thinking Required to embrace it !

Simpson's paradox : the fundamental assumption that things are absolute needs to be resolved ....things are relatively depending ...even causality ....human logic has to evolve ! Infact human thinking logic is linear and unable to incorporate Paradoxical realities of Nature....It needs not be resolved rather human thinking logic has to embrace non linearity and paradoxical relative reality rather than absolute casuality...

Nature is also fundamentally Paradoxical ..Human analysis needs to broaden its logical linear thinking to remain incompatible ! Paradoxes are the Realities of Nature !

No matter how many causes discover, paradoxes would always remain in one or the other forms, being the fundamental characteristics of Nature.

 What is a paradox: when things start appearing Inconsistent/self - contradictory to human logic Al linear thinking ...but that could be how Nature really is !

Things are indeed Inconsistent/ incomplete in Nature ..Human logical thinking has to evolve !

Every statistical relationship between two variables may be reversed by including additional factors in the analysis and that lacking causal information of the context, one can not be sure what factors should be included in the analysis....

But the problem is not just about the limitations Incompleteness and Inconsistency of statistical methods but deeper about causality and human logical linear  thinking itself that demands to embrace the Fundamental Inconsistency/ Incompleteness/ paradoxical nature of universe. 

In complex non linear world, there may always come up new unknown causal factors that could reverse the relationship leading to Incompleteness of causal factors and Inconsistency in the relationship ! No absolute causality ! Relative causality ! Fundamental characteristic inherent in the Universe.

So, it's not just Fundamental limitations of Statistical Tools rather limitation of Human Logical Causality as well and Human Logical Thinking will have to embrace foundational Incompleteness and Inconsistency inherent in the Universe like Godel one.
