I graduated from high school and wish to further my education formally by studying for a bachelor's degree in order to become a medical researcher. I could, for instance, take two different academic paths:

1. Study Medicine at undergraduate level and then do a postdoctoral fellowship.

2. Study Biochemistry at undergraduate level, then study for a PhD at graduate level, and finally do a postdoctoral fellowship.

Since I will do these studies in Europe, they each take approximately the same amount of time, namely 6 to 8 years.

Do I want to do treat patients? No, I do not. But I am considering Medicine because it can be a buffer against my own mediocrity: in case I turn out to be a below average scientist, I will be screwed royally. From my personal job shadowing experience, Medicine, on the other hand, requires mere basic intellectual traits, primarily the ability to memorize heaps of information. And those I think I have. To do world-class research though I'd have to be an intellectual heavyweight, and of that I'm not so sure.

How do I decide what path to  follow?

The reason I'm asking you strangers for advice is because I evidently have biases, such as the pessimism/optimism bias or the Dunning–Kruger effect, that impair my ability to reason clearly; and people who know me personally are likewise prone to make errors in advising me because of biases like, say, the Halo effect. (Come to think of it, thinking that I can't become an above average scientist is in itself a self-defeating prophecy!)

Do you think that one ought to always seek advice from total strangers in order to be safeguarded from his/her own biases?

PS: I apologize if I should have written this in a specific thread. I'll delete my article if that's necessary.
