What exactly is thinking? It turns out this is an area where you can’t trust dictionaries to provide meaningful definitions. If you consider the various definitions of the word—or the process—you’re likely to either be confused or to grab one that fits your existing concept so you (and your not-necessarily-thinking brain) can move on.
I don’t want to get philosophical about it, but I think there’s value in acknowledging the confusion. Being able to think clearly and effectively is essential for anyone who wants to lead a satisfying and meaningful life. It’s the difference between using your brain and letting your brain use you.
Warning! Metacognition* Ahead.
One definition equates thinking and opinion. But that source also equates opinion and judgment, so my opinion is that their thinking is sloppy and can’t be trusted. Are they referring to opinions and judgments rendered as a result of careful deliberation or are they referring to off-the-cuff (and often off-the-wall) moment-to-moment opinions and judgments that result from jumping to conclusions based on little or no evidence?
Another source says thinking is the action of using one’s mind to produce thoughts. This sounds reasonable, but I’m not sure what they mean by “using one’s mind.” Based on the way the two parts of the brain work, we know that the majority of thoughts we have are suggestions from System 1 (the unconscious) rather than the result of conscious deliberation.
Yet another definition equates thinking with having a conscious mind. But there’s a difference between consciousness and both the contents of consciousness (what you’re aware of—see above) and conscious processes. You’re conscious of all kinds of things you’ve never given any particular thought to.
For example, I’m aware that I dislike the color pink and rainy climates. I’m also aware that I’m suspicious of people who prefer rainy climates. But I’m not under the impression that any actual thinking was involved in the development of those so-called “thoughts.”
How Do I Think?
Let Me Count the Ways.
Some of the confusion undoubtedly results from the fact that, as with memory, there are so many different types of thinking that the term needs adjectives to clarify and differentiate them. Variations on the theme of thinking include:
- Critical thinking
- Associative thinking
- Ruminative thinking
- Creative thinking
- Default-mode thinking
- Counterfactual thinking
- Overthinking
- Positive thinking
Critical thinking is the ability to think clearly, rationally, and objectively and to understand the logical connection between ideas. It’s an active rather than a passive process. Because it requires System 2 (conscious) attention, it doesn’t come naturally and isn’t easy. In order to make an important decision or solve a significant problem, you need well-developed critical thinking skills so you can effectively evaluate both the information at hand and the “intuitive” suggestions spontaneously arising from System 1.
Associative thinking is the process System 1 (the unconscious) uses to link one thing (thought, idea, experience, etc.) to another. Associative thinking is much faster than logical, linear thinking, and there are times and places when quick, non-reflective responses are required. But there are some built-in problems with associative thinking. It sacrifices accuracy for speed, so the patterns it sees and the connections it makes don’t always lead to useful conclusions. It doesn’t discriminate very well, preferring clear-cut distinctions rather than shades of gray. And it takes numerous cognitive shortcuts known as cognitive biases.
Ruminative thinking is the tendency to passively think about the meaning, origins, and consequences of negative emotions (Nolen-Hoeksema, 1991). One negative incident or thought leads to another, and the escalating intensity of negative thoughts can result in depression, aggression, or even an increase in physical pain. You can ruminate about situations, other people, or about yourself (self-rumination). Rumination can feel like problem-solving, but all it does is keep you focused on the problem. The danger is that it can become a habit—and habits are notoriously difficult to change.
Creative thinking (or creativity) is the ability to see what already exists in a new light, to think of new ideas, and to make new things. This is less a talent or gift than an approach to life, and it provides many rewards apart from the products of creativity. Creative thinkers are less likely to be bored, more likely to have greater problem-solving abilities, and are very likely to get more general enjoyment out of life. The key to creative thinking is to know when to use logical, linear (System 2) thinking and when to use associative (System 1) thinking.
Counterfactual thinking is thinking that runs counter to the facts. It consists of imagining outcomes other than the ones that occurred: the way things could have been—or should have been—different from the way they turned out. Being able to imagine different outcomes is an enormous evolutionary and practical advantage. It’s integral to being creative or inventive and in not continuing to make the same mistakes over and over again. Counterfactual thinking can be either functional (helps you figure out what to do next time) or nonfunctional (leads to blame, stress, anxiety, etc.). And it can be either upward (how could things have gone better?) or downward (how could things have gone worse?).
Default-mode thinking is the opposite of mindfulness. Although you can sometimes direct your mind to focus on what you want it to focus on, at other times it just wanders along a winding path on a trajectory of its own. That’s because whenever you’re not focused on an external task—and even sometimes when you are—the network of brain structures referred to as the Default Mode Network (DMN) is active. Mind wandering isn’t the same as being distracted. In fact, default mode thinking is essential for consolidating memory and maintaining your sense of self (who you are).
Overthinking is often the result of believing you can fully determine—or even guarantee—an outcome based on the amount of thinking you do about it. It often consists of making multiple lists of pros and cons, running through if/then scenarios, trying to gather as much information as possible, or attempting to approach an issue from every conceivable angle. This is not an effective approach to planning or decision making because thinking more or thinking harder doesn’t lead to clarity, only to confusion and possibly a headache. Too much logical, linear thinking can be as bad as too little.
Positive thinking is usually defined as a mental attitude that accentuates the positive and eliminates the negative. Supposedly, positive thinking can help you succeed and better deal with life’s upsets and challenges. However, a considerable amount of research has come to a different conclusion, which is that positive thinking may be more of a hindrance to success than a help. Positive thinking isn’t the same as optimism, which is a character trait. Positivity and optimism are desirable, but not to the point where your glasses become so rose-colored you’re unable to see through them.
*Metacognition means thinking about thinking as opposed to reacting to it or being at the effect of it. The part of the brain that runs you most of the time (the unconscious) initiates both thoughts and actions that serve to maintain your personal status quo. So if you want to change the status quo, you need to determine what kind of thinking you’re doing—or what kind of thinking is “doing” you.
