There is a quiet tension in knowledge work. Throughout the day we are constantly getting new inputs, as emails, phone calls, and messages stack up. However, we also must spend time making decisions in order to move forward on our goals and projects. Focus too much on the first and we make little progress on important goals. Focus too much on the later and the stress of overflowing inboxes weighs heavy on our minds. Therefore, must we make a choice? Is one of these more important than the other?

In a post on his Substack page, GTD creator David Allen considered the apparent paradox that knowledge workers face between processing new input and making decisions on objectives. He ultimately finds they are not in conflict at all. That is because they occupy different spaces in workflow. To start with, Allen believes it is important to process new input when it first shows up.

When you put off this thinking for longer than a day (or two or three or more), the more mental effort it will take to reconstruct what that input was about and reduce or eliminate your backlog. Research on memory suggests that if something is more than seven days past, it’s extremely difficult to remember or recreate what happened, and what it’s about. Not a long time. but magnify that by as many unprocessed things you have. If you zero out your in-baskets daily, it’s not such a drain on your energy to get things clear. 

Keep in mind that processing an item is not the same as making a final decision on it. While some two-minute rule items can be dispatched quickly, for more complicated projects there is an advantage to delaying a decision. In fact, letting it marinate until the deadline may be more productive in the long run.

There are times and situations in which it could be more productive to wait to engage with making a decision or acting on something until it would be critical if you don’t. This is particularly true when new information is likely to arrive that would change your call. …

On a more subtle and strategic level, it could mean waiting for the environment to shift before making a judgment call that would have lots of impact. 

Allen summarizes this approach in a simple phrase: Clarify fast, decide patiently. Do this and the tension will dissolve as you work with a mind like water.
