Is a phenomenon in which researchers hypothesis let them to unintentionally by succumb of a study?

It seems you're referring to the "hypothesis confirmation bias," where researchers may unintentionally design studies that favor their hypotheses, leading to biased results. This phenomenon can occur if researchers selectively interpret data or overlook evidence that contradicts their expectations. Such biases undermine the objectivity of scientific research and can lead to misleading conclusions. To mitigate this, researchers should adopt rigorous methodologies and remain open to unexpected findings.
