There's a guy in every family who sends email to the world containing some note from someone else on the Internet with an amazing fact. In my case, the guy apparently believes anything negative about Democrats, even though the family regularly suggests he goes to Snopes before sharing this information and embarrassing himself. His latest note suggests that Bill Clinton had to be pardoned because he criminally avoided the draft, making him the only felon President. Like most of the other "facts," it was utter BS, but off it went. I'm left praying no one I know find out we're related.Unfortunately, this isn't an uncommon problem. It even has a name: Confirmation bias. Some of the worst decisions I've made in my life \u2014 buying motorcycles, cars and even homes \u2014 happened without thinking. I put all my information into a bucket that confirmed I was right, even though I wasn't. It took me a few years to learn my lesson, but now I generally check and double-check a decision and often find that the path that looked the best wasn't at all because I hadn't stepped back and considered all the facts.This is where IBM's Watson could make a great contribution. So many truly horrid business decisions, from acquisitions to product strategies, have resulted from a combination of confirmation bias and argumentative theory. (The latter argues that the biggest jerk at the table must win an argument, lest he lose status, and tends to favor not appearing to be wrong over actually being right.)It's Human Nature to Shoot First, Ask Questions LaterWe've accomplished a number of amazing things as a race, but to say we are flawed as a race would be an understatement. Most troubling is the tendency to reach a conclusion quickly, then look for reasons to defend that decision. This does a great deal of damage.Years ago, on a Siemens competitive analysis team, we briefed executive after executive on why the current strategy was going to fail spectacularly. Through hard research, we convinced every executive that we were right. They'd return to Germany, but instead of getting to fix the strategy, the executives got reassigned, and a new believer was sent to us. This happened three times before Siemens fired us \u2014 and then burned $5 billion, proving us right.\n[ Related: Forced Rankings Are Institutionalized Stupidity at Its Worst ]\n[ More: Data Analytics Will Fail If Executives Ignore the Numbers ]Siemens' strategy was based primarily on the theory that ISDN would replace Ethernet as the prevalent networking standard. The rest read like something so unbelievable it would probably get rejected as a script for The Office, yet this PhDs \u2014 and they mentioned their degrees often \u2014 not only couldn't see it but wouldn't see it.My most famous (or infamous) situation involved Windows Vista. I constantly said it wasn't ready and would fail if something wasn't done. (A later lawsuit made all those emails public.) Microsoft thought I was crazy \u2014 until the product launched and crashed in market. I was hardly the only one who saw that train wreck coming. But everyone else not only didn't see the signs; they refused to see the signs. The result was a boom.Watson Can Make Us Smarter (If We Let It)Watson, as you know, is IBM's thinking computer. This week, IBM presented something called Watson Jr. that will make Siri look stupid by comparison. But it's the next generation of this product that I find fascinating, because Watson is being taught how to reason.Watson will have access to all the information you have \u2014 and it won't have confirmation bias or a need to gain status by appearing to be right. In effect, this cognitive computing will give us the equivalent of a "Stupid Alert" and be able to tell us when we're doing something we will later very much regret. This may be its most useful feature \u2014 and it could very well save the world:I recall a Senate hearing at the close of the Iraq conflict during which one general said rebuilding the country would cost more than the war itself. He was laughed into retirement \u2014 but he was also dead right.\nScientists build larger and larger particle colliders and put them through much more rigorous experiments than they were originally designed to handle. I don't know about you, but when it comes to the death of our planet, 1,000-to-one odds, even if flawed, don't seem very reasonable. It's not like we can relocate.\nGlobal warming is a contentious issue, and one side of the debate seems to be more correct than the other, but it would sure help to know which site is, in fact, right before we are all dead. (Granted, the problem pretty much solves itself at that point.)[ Report: Supercomputer Nautilus 'Knew Where Bin Laden Was' ]Watson should make us smarter. That's my hope. But I'm reminded of my Siemens example. In the face of a global catastrophe, if Watson told us that popular opinion was wrong, would we turn it off, thinking, "Gee, that can't be right"?It sounds like a plot from The Outer Limits \u2014 and I sure hope for the sake of us all that it isn't also prophetic. Watson could assure our future. I wonder if we're too human to let it.Rob Enderle is president and principal analyst of the Enderle Group.
