All of a sudden the world could be delivered in a spread sheet. You can see how many people visit your site, what pages the visit, even tell which color font people prefer! It was pure bliss.

Why We Make Mistakes Blog: March 2009

http://whywemakemistakes.blogspot.com/2009_03_01_archive.html

Friday, March 6, 2009. The Power of Regret. If you saw Paul Krugman's column. Today, he took the Obama administration to task for its inaction on dealing with zombie banks those so badly wounded they resemble the walking dead. This tendency was illustrated in a series of experiments. But more important is what the students revealed in follow-up interviews. The prospect of changing a right answer to a wrong one filled them with much more regret than the prospect of failing to change a wrong answer to ...

Why We Make Mistakes Blog: Left to Our Own Devices...

http://whywemakemistakes.blogspot.com/2011/10/left-to-our-own-devices.html

Thursday, October 13, 2011. Left to Our Own Devices. In case you missed it, let me direct your attention to a recent page-one story. In The Wall Street Journal. The article documents a growing trend among surgeons to implant their own medical devices into the bodies of their patients. As a result, the surgeons stand to profit twice: once from the surgery and again from the sale of the device. Perhaps. But nearly every piece of research on the subject points the opposite way. The interesting thing is that...

Why We Make Mistakes Blog: August 2009

http://whywemakemistakes.blogspot.com/2009_08_01_archive.html

Wednesday, August 26, 2009. One of the most common sources of human error is multi-tasking, especially when performed behind the wheel of a car. DWT or Driving While Texting, is a supremely bad idea; it's been implicated in the crash of a train in Los Angeles and a trolley in Boston. It is also becoming illegal. In Utah, for instance, texting and emailing while driving are now punishable by a $750 fine and 90 days in jail. The state has put out a video, which you can see here. Appearing now in the U.K.

Wednesday, February 4, 2009. That’s the cap on compensation that the Obama administration wants to impose on top executives whose companies get big bailouts from the government. No doubt, some will say this is a mistake that these companies won’t be able to attract and retain talented workers without paying the enormous bonuses of the past. Quite a few studies in recent years. Posted by Joe Hallinan at 11:31 AM. View my complete profile. Why We Make Mistakes. Another Thing That Doesnt Work.

Why We Make Mistakes Blog: A Rigged System

http://whywemakemistakes.blogspot.com/2011/06/rigged-system.html

Thursday, June 23, 2011. If you want to see a good example of how bias warps decision-making, check out this article. In The Wall Street Journal, which has been reporting on developments regarding medical device giant Medtronic Inc. (Disclosure: I have friends and family who work for medical device makers.). But academic research suggests otherwise. As Princeton professor and Nobel Laureate Daniel Kahneman and colleagues note in a recent article. And in the case of Medtronic, those are quite some interes...

Why We Make Mistakes Blog: December 2008

Sunday, December 14, 2008. Dec 16 Bernie Madoff With A Lot of Money But How? That’s the question on Wall Street these days as investors (not to mention federal prosecutors) try to figure out how so many supposedly smart people were duped out of so many billions of dollars. One clue comes from William Goetzmann, a finance professor at Yale whose work was recently highlighted in The Wall Street Journal. In other words, investors were getting useful information they just weren’t paying attention to it.

http://whywemakemistakes.blogspot.com/2011/04/mis-directions.html

Tuesday, April 26, 2011. Why We Make Mistakes. I have a little fun pointing out how often people fail to follow the instructions that come with a variety of products, from nail guns to car seats. But if you want an even scarier example, check out today's story. In The Wall Street Journal on drug labeling. Often, this leads to a trip to the hospital. Nearly 1.9 million people were treated in hospitals for illnesses and injuries from taking medicines - a 52% increase from 2004 to 2008. They had a great loo...

Monday, September 20, 2010. Looking on the bright side. Why We Make Mistakes. I talk quite a bit about our tendency not only to err, but to err in a particular (and predictable) direction - and that direction is toward optimism.

Tuesday, May 26, 2009. The Folly of Texting. There have been a number of stories in the press lately on the follies of texting while doing almost anything else. One of the more recent.
