What does the Slippery Slope fallacy assume?

The Slippery Slope fallacy assumes that taking a single action will inevitably lead to a chain of negative consequences without providing sufficient evidence to support that claim. This type of reasoning suggests that a relatively small first step can lead to a chain of events culminating in significant and often undesirable outcomes. For example, if someone argues that allowing students to redo exams will eventually lead to a complete disregard for academic rigor, they are demonstrating the slippery slope fallacy by assuming that one action will unavoidably lead to a series of negative results.

The other options do not accurately capture the essence of the Slippery Slope fallacy. The assumption of a simple causation leading to dire results is the hallmark of this fallacy, rather than the concepts of argument validity, emotional support for arguments, or biases against certain topics. Each of those elements pertains to different types of reasoning or logical errors, distinct from the core principle underlying the slippery slope argument.
