This is a very interesting question. At first glance this question seems like an oxymoron, because technology is to help decision making and productivity. But if we think about how technology works, at times we might conclude that it hinders decision making. Let me give you a few examples.
First, I believe sometimes too much information - especially information that is not worth knowing - can hinder decision making. Through the use of information technology, there is simply too much information on all topics that often times people are stifled in decision making due to a paralysis of analysis. This is all the more important, when decision need to be made quickly.
Second, through technology there are just too may option for pretty much everything. For example, say a person wants to go on vacation, this person can go virtually anywhere in the world through the use of planes, trains, and ships. All of these technologies are great, but the sheer number of options hinders people from making a decision and more importantly at times (from a emotional level) hinders them from enjoyment.
