Taqlid
Taqleed generally refers to blind following of our ancestors without questioning, even when evidence is to the contrary. This is not a healthy behavior, and quite contrary to the spirit of Islam. Even Quran argues against such behavior and motivates people to use their intellect to infer things on the basis of evidence. Please see Quran 25:72-73 for an example.
We go to a medical professional to get ourselves treated, and we have no way to examine the correctness of his prescription. Here, we can very well analyse all the arguments and make judgments based on our reason, that which scholar is making more sense, on a particular issue. Allah asks us to use our reason.
