Can it be rational to favour the status quo when the alternatives to the status quo promise considerable increases in overall value? For instance, can it be rational to favour the status quo over radical human enhancement? A reasonable response to these questions would be to say that it can only be rational if the status quo is indeed the better choice on some measure. In this paper, I argue that it can be rational to favour the status quo over (...) a radical improvement such as human germline genetic enhancement. First, I distinguish between three different meanings of the “status quo.” Then, I argue that the status quo enjoys modal and epistemic advantages that sometimes translate into other advantages. I propose eight parameters for comparison between the status quo and radical options. These parameters weigh in favour of the status quo but can be outweighed by the benefits of change. Each of these parameters needs to be assessed from case to case. I defend what I refer to as an Open Status Quo position over a Fixed Status Quo position. The former is decision-specific and does not entail a commitment to remaining with the status quo in later decisions. Lastly, I address the objection that an Open Status Quo position risk slipping into a Fixed Status Quo position that would, in turn, block radical progress, change, and discovery. (shrink)
