How much scientific interest should I demonstrate in a Medicine personal statement?

Medicine personal statements should generally include some evidence of you independently pursuing any scientific interests that you have may have. This may include reading popular science literature, doing an extended project or attending lectures/talks. The amount of weighting that you give this in your personal statement depends largely on the expectations of the specific Universities that you are applying to. For an Oxbridge application for example, it is generally advised to include at least one large paragraph on this matter with some specific reference to a topic or idea that you found particularly striking in the book or lecture to demonstrate that you engaged with it. However, it is important not to forget the social aspect of Medicine and you will likely get brownie points for integrating the scientific and social allure that Medicine has for you, for example by dwelling on the social implications of a piece of research that you have read about.
