I describe a way to understand vipassana meditation (a form of Buddhist meditation) using the concept of affective judgment1.  Vipassana aims to break the habit of blindly making affective judgments about mental states, and reverse the damage done by doing so in the past. This habit may be at the root of many problems described on LessWrong, and is likely involved in other mental issues. In the followup post I give details about how to actually practice vipassana.

The problem

Consider mindspace. Mindspace2 is the configuration space of a mind. Each mental state is identified with a position in mindspace, specified by its description along some dimensions. For human mindspace the affect of a mental state is a natural dimension to use, and it's the one that's most important for a conceptual understanding of vipassana meditation.

According to vipassana meditators, every time we pass through a point in mindspace we update its affect by judging3 whether that mental state is good or bad. On the other hand, the path we take through mindspace is strongly determined by this dimension alone, and we tend to veer towards clusters of positive affect and away from those with negative affect. The current judgment of a mental state is also strongly determined by its present affect. This can result in a dangerous feedback loop4, with small initial affective judgments compounding into deep mental patterns. It seems that this phenomenon is at the root of many problems mentioned here.5

Aside from causing systematic errors in thought and action it is claimed that this mechanism is also responsible for our mental suffering and restlessness. Vipassana aims to solve these problems by training us to observe and control our affective judgments, and break out of the pattern of blind reaction.

How it works

There are four aspects to the process:

  1. Slowing the flood of affective judgments so one can distinctly observe them.
  2. Learning to not compulsively make affective judgments.
  3. Smoothing one's previously formed emotional gradients.
  4. No longer forming strong emotional gradients.

They are synergistic practices and should be developed simultaneously. This will only be possible later on; at any given time you may only be able to practice one or more of them.

1) Slowing the flood

The ability to calm the mind and concentrate is essential. Without this, one remains involved in the rushing pattern of affect perception and judgment, and there is no possibility of seeing the process and ultimately changing it. This ability is trained by having one maintain awareness of a neutral mental process, which serves as an anchor that one continually returns to. Gradually one becomes aware of the subtle pattern of affective judgments and can distinctly observe them.

2) Not compulsively judging

While periodically returning to the mental anchor, one attempts to observe the mental states that arise without making affective judgments about them. In trying to do this it becomes clear how such judgments can cascade and create deep mental paths that it can be hard to escape from.

3) Smoothing old emotional gradients

Applying this new skill of neutral observation, one works on the long task of undoing old emotional gradients. When observing a mental state without making an affective judgment one can lower6 its present affective value. This is opposed to the previous pattern of making another affective judgment in the same direction, and increasing (or sustaining) its affect. A great variety of mental states will arise during this process, and by neutrally observing them one slowly dismantles the affective structures that are widely distributed in mindspace.

4) No longer forming strong emotional gradients

While smoothing old emotional gradients one must take care not to create new ones. The goal is not to never make affective judgments (I'm not even sure this is possible), but rather to take control of the process and prevent dangerous feedback patterns from occurring.


Vipassana meditation aims to change the way we assign affect to mental states, and reverse the damage accumulated from doing so poorly in the past. Our default way for doing this may be the root of a number of rationality problems. Vipassana serves as a meta-tool, helping one to defuse harmful affective structures that are causing particular problems. I expect that these are common but vary in intensity, and the benefits of vipassana are obtained mainly through correcting these "pathologies".


1 My basis for using this concept is mainly introspective observation during my daily meditation practice the past three years. At the very least I expect it will be helpful for understanding and practicing vipassana meditation, but it may turn out to be a fundamental cognitive process.

2 Note that this concept is distinct from mind design space. In mind design space each point corresponds to a possible mind, and hence each point has an associated mindspace.

3 For a simple case where the distinction between making an affective judgment and not making one is clear, consider experiencing a painful sensation. I claim that this pain is actually a composite phenomenon; it consists of a strong negative affective judgment (or series of such judgments) and a physical sensation. Not making an affective judgment in this case would mean that all that remains is the physical sensation. You would keep experiencing this physical sensation but not have a dying urge to do something about it (like shift your sitting position, for example). As long as you make sure that you are not causing bodily damage, I think that observing pain in meditation can be a really great learning experience.

4 In Buddhist literature the positive feedback spiral is called craving and the negative one is called aversion.

5 Don't forget this and this. This phenomenon may also be responsible for the cached thoughts and cached selves problems, depending on the degree to which cached mental structures are implemented as emotional gradients.

6 This is meant in the sense of absolute value.


Edit: On Academian's recommendation I've added a footnote attempting to clarify the notion of an affective judgment, and what it means not to make one. It's an excerpt from my comment here.
