Israel-Gaza Megathread #2
This is a refreshed megathread for any posts on the conflict between (so far, and so far as I know) Hamas and the Israeli government, as well as related geopolitics. Culture War thread rules apply.
The failure rate on, say, CCTV cameras is high enough that it’s not tenable.
Source: my manager was assigned to Afghanistan as a surveillance contractor. He noted that they had to run the cables between cameras at the top of the walls, or rats would chew them overnight. And they’d still try their best to get at the anchor points.
The whole point of running a surveillance system is to freak out when something goes wrong, even if it's rats 99.9% of the time. We have a burglar alarm at our summer cabin and so far it has been triggered only by power loss or by one of the family members tripping it because the were deep in their thoughts. I am sure it's the same for everyone else in the area and a sign that says "This home is protected by Unity Security Services" is enough of a deterrent. But the deterrent only works if you actually know that if you trip the alarm, the patrol will be there quicker than you can get that TV over the fence, even if 99% of the time they are met by the embarrassed owner who really had to take a dump pronto.
Or take fire drills. Can you imagine how terrible it is to walk all the way from the 70th floor of your skyscraper after you've sprained your ankle jogging? You need to find that weird-looking wheelchair with grippy runners, find someone willing to push it down one hundred and thirty eight flights of stairs, it's always raining when there's a fire drill because why wouldn't it, and then you have to limp back to the elevators and explain to your boss why your report is overdue. You sprain your ankle on September 10th, 2001 and limp to work the next day.
That's a fine theory, but it goes against human nature to expect people to not detect patterns like: each time I investigate, it turns out to be a rat. So you then need a mechanism to prevent people from acting normally, which is a hard problem to solve.
This website is a place for people who want to move past shady thinking and test their ideas in a
court of people who don't all share the same biases. Our goal is to
optimize for light, not heat; this is a group effort, and all commentators are asked to do their part.
The weekly Culture War threads host the most
controversial topics and are the most visible aspect of The Motte. However, many other topics are
appropriate here. We encourage people to post anything related to science, politics, or philosophy;
if in doubt, post!
Check out The Vault for an archive of old quality posts.
You are encouraged to crosspost these elsewhere.
Why are you called The Motte?
A motte is a stone keep on a raised earthwork common in early medieval fortifications. More pertinently,
it's an element in a rhetorical move called a "Motte-and-Bailey",
originally identified by
philosopher Nicholas Shackel. It describes the tendency in discourse for people to move from a controversial
but high value claim to a defensible but less exciting one upon any resistance to the former. He likens
this to the medieval fortification, where a desirable land (the bailey) is abandoned when in danger for
the more easily defended motte. In Shackel's words, "The Motte represents the defensible but undesired
propositions to which one retreats when hard pressed."
On The Motte, always attempt to remain inside your defensible territory, even if you are not being pressed.
New post guidelines
If you're posting something that isn't related to the culture war, we encourage you to post a thread for it.
A submission statement is highly appreciated, but isn't necessary for text posts or links to largely-text posts
such as blogs or news articles; if we're unsure of the value of your post, we might remove it until you add a
submission statement. A submission statement is required for non-text sources (videos, podcasts, images).
Culture war posts go in the culture war thread; all links must either include a submission statement or
significant commentary. Bare links without those will be removed.
Jump in the discussion.
No email address required.
