A level revision

Slippery slope

One thing leads to another, setting off a chain of events or actions from a single original event. A slippery slope flaw reasons that because the 'last link' in such as a chain is bad so is the original event. If the original event could possibly lead to the last event then this reasoning is not fallacious, the flaw occurs when the original event is not properly linked to the last event by making extreme and unjustified jumps. For example:

You should do some revision, if you do not get a B in your A level exams you won't be able to go to University and so won't be able to get a job and die a homeless man

Here the links between events are far too extreme to be valid, not getting a B may stop you from going to your university of choice however to jump from this to not being able to get a job is unjustified.

Slippery slopes aren't always negative, turning the above exam around:

You should do some revision, if you get a B in your A level exams you'll be able to go to University and get a job paying £100,000 and die a millionaire.

This argument is as bad as previous, even if the last link in the chain is seen to be 'good'
