Timing is equally important when training with negative reinforcers. The horse learns to turn left when the left rein is pulled, but only if the pulling stops when it does turn. The cessation is the reinforcer. You get on a horse, kick it in the sides, and it moves forward; you should then stop kicking (unless you want it to move faster). Beginning riders often thump away constantly, as if the kicking were some kind of gasoline necessary to keep the horse moving. The kicking does not stop, so it contains no information for the horse. Thus are developed the iron-sided horses in riding academies that move at a snail’s pace no matter how often they are kicked.
The same applies to people getting nagged and scolded by parents, bosses, or teachers. If the negative reinforcer doesn’t cease the instant the desired result is achieved, it is neither reinforcing nor information. It becomes, both literally and in terms of information theory, “noise.”– Don’t Shoot the Dog, Karen Pryor

Here’s hoping they keep working on it, but please, save your pre-order money.
#3. That Anti-Date-Rape Nail Polish Doesn’t Exist
According to the articles on the subject, this new fashion accessory helps women prevent date rape by changing color when exposed to drugs like Rohypnol, Xanax, and GHB. As The Washington Post, CNET, USA Today, CBS, and Mashable wonder: does the nail polish help prevent the crime of rape or perpetuate the idea that the onus of prevention lay solely on the victim? Well, here’s Cracked’s take on the subject: it doesn’t matter, because the nail polish totally doesn’t work. Or exist.
According to the project’s creators (four students at North Carolina State University), the thing is actually in an “early R&D” stage, which is another way of saying that it isn’t actually a thing. And if it were? Turns out that only about 3 percent of urine samples from assault victims carry traces of the drugs it detects — or “detects,” since the technique they’re using is notorious for giving false positives. Remember those date-rape preventing coasters? Yeah, they can turn color when exposed to water.
The truth of it isn’t all Macklemore and funny coats and tiny bicycles.
#4. The Wealthiest Customers Are the Worst
The thrift store I worked at was in a really wealthy neighborhood, so obviously we got a solid handful of rich, bored housewives who’d come in out of idle curiosity for how the other half lives (spoiler alert, rich people: not as well as you). The wealthy customers would talk to me as if being around donated clothes meant that I was also some kind of discount, donated human. One such woman sneered when I told her an Abercrombie shirt was $2.99, because she expected it to be free, apparently. After I finished ringing her up, she stood by the register and pointed out every dismal aspect of our store like a judgmental stepmother.
Listen carefully. Everyone make mistakes. But if you committed a sin, you have to make an atonement for that sin. Atonement, do you know what that means? Big Atonement for big sins. Small Atonement for small sins.
