The Slippery Slope fallacy: the one we’ve never got on with

“Don’t throw that rubbish there! Put it in the bin like you’re supposed to!” Many years ago we lived on a pleasant private estate in West London with trimmed lawns, walkways, security, a residents association, all those sorts of things. The only problem was some of the residents, who were either too lazy or felt culturally compelled to throw their domestic rubbish down by the rubbish chutes instead of putting in properly, as we, the decent majority did. This bad practice spread, being quickly copied across the estate and soon we all had a widespread problem with flies, rodents and an ugly disfigurement of our pristine areas. It’s called the slippery slope. Another example is when the office agrees to step out for a single drink and, three hours later, the entire company ends up blind drunk ,broke and embracing each other with varying declarations of love. Everyone copies bad behaviour, because they feel entitled, or are missing out. And so crime, disorder, drugs and violence spread quickly through communities, reducing everyone to common beggary.

And that raises a bigger problem for us here at LSS. For years we have proudly touted our Enlightenment, Whig, rational, call them what you will credentials like a badge of honour. Central to our purpose, hardened readers will recall, is the practice of reason and logic. Avidly do we follow websites like your logical fallacy which are stuffed with every classic example you could wish for: post hoc propter hoc, texas sharpshooter, all shining beacons of clear thought each one of them.. Standing out like a dead rat in a melon souffle is the slippery slope, of which the authors state

Allowing to happen will cause Z to happen: therefore we should ban A now!

Yes, we see the error. The slippery slope is a fallacy for it allows one to jump to conclusions without checking each intervening link from A to Z for both logic and empirical fact. Its the classic howler of someone like a Daily Mail columnist, carried away on tides of hysteria and dread. The trouble is: it’s how humans really behave. It’s the way most of them are.

So our problem with the slippery slope mirrors a more general problem. Reason, learning, and all the the qualities which we prize are not always good guides to how society works. (Try a Friday night out in Croydon if you don’t believe us) Yet the values we espouse are the only ones which will ensure not only the good life but also human survival in the long term. The problem we now have is how do we form a critical mass to allow those values to prevail?
