Looking at the history of politics and law, it looks like slippery slope arguments are right more often than they're wrong.

That's really vague. Examples would help, preferably ones from long ago so as to avoid the mind-killer: for instance, the Reign of Terror could be an example of a slippery slope.

The other side, of course, is that not all slippery slopes lead to bad outcomes- consider the civil rights movement.

Anyway, of course every policy change affects the likelihood of other policy changes, but only occasionally is it a runaway effect- usually it stops there or peters out.

That's really vague.

Senses of history are vague, but still informative. It's not clear to me there's much value in digging up examples.

preferably ones from long ago

I don't consider 1950 to be long ago.

that not all slippery slopes lead to bad outcomes

No, and I did not mean to imply that they did. Many intentionally begin slippery slopes to lead to outcomes they like; foot-in-the-door techniques can be seen as an example. The takeaway is that the slippery slope meme doesn't appear to actually be fallacious- if you think that A will increase the chance of B, and you dislike B, it's often the correct strategic move to oppose A, even if you think A in isolation is a good thing. The challenge is getting the correct model of how A will impact the chances of B.

I don't think we disagree here. As far as 1950 being "long ago", my point was that I picked examples that I really don't expect to be live issues for Less Wrong readers; there were other issues being discussed in 1950 that are still subjects of disagreement between LW-type people, and those I shouldn't use.
