I’ve finally come to realize that I make my best decisions in the morning and my worst decisions in the afternoon or evening. The reason for this is a phenomenon called decision fatigue . It’s the idea that the more decisions that you make during the day, your ability to make good quality decisions rapidly decreases as the day wears on. I used to think that living in a world with a myriad of choices available was a fantastic opportunity, but sometimes it is the availability of the huge number of options in our lives that can be overwhelming. I think that these ideas can feed into procrastination, especially when there are so many choices competing for our attention. I also wonder if this is partly driving why many of my students are so unclear about their next steps in education, life, and career. The more decisions that we have to make, the harder those decisions become.
So what can you do about decision fatigue and/or avoid it? This article at the Huffington Post provides some simple steps. I think that the best suggestion is to make important decisions in the morning when you are still fresh and have a large supply of willpower. The other hint that I think is helpful is to limit yourself to three options only and make a decision based on those. I’ll often do this when buying lab equipment. I’ll first think about the features that the item really has to have and only look at options that satisfy these criteria. This makes it easier to make decisions and feel good about them and avoids the trap of second guessing my decisions after I’ve made them.
The negative consequences of decision fatigue can be high. Maybe it’s starting a research project that ends up being a time, money, and resources sink. Sometimes it’s a bad equipment purchase. It could involve sending your manuscript to an inappropriate journal. Bad decisions are costly for a number of reasons; I do my best to avoid them by consciously choosing to make important decisions about work when I first arrive at work. A fresh brain is a brain that’s capable of making better choices.
