What are Some Challenges in Identifying Causal Mechanisms?
Identifying causal mechanisms is fraught with challenges:
Confounding: Other variables may be responsible for the observed association. Bias: Selection bias, information bias, and other forms of bias can distort findings. Complexity: Many diseases have multifactorial causes, making it hard to isolate specific mechanisms. Ethical Constraints: Some experiments may not be ethically feasible to conduct in humans.
