The Neuroanatomical Correlates of Self-Sabotage

Self-Sabotage, by jesse.millan

I should be preparing for a Very Important Presentation at an upcoming meeting. But I'm not. I'm sitting at home on a Saturday night, blogging about self-sabotage.

"Self Sabotage is when we say we want something and then go about making sure it doesn't happen."

I do have a lot of clever ideas and useful data that are relevant for the meeting in question, I just haven't been able to start preparing my presentation yet. Am I afraid of failing? Angry at the complete lack of incentive structures at my workplace (which is organized and run in such a laughably inept manner as to be totally demotivating)?


Psychology of Self-Handicapping

What is behind the act of setting yourself up for failure, for unconsciously compiling a list of excuses for why you didn't perform at your best? What motivates this behavior?

It's an act of self-preservation, actually, to have external reasons for why you didn't achieve what you set out to accomplish. That way, you're not a complete and total failure as a person. It protects your fragile self-esteem, but this comes at a price.

Zuckerman and Tsai (2005) found the long-term costs of this strategy include a loss of perceived self-competence, negative mood, increased substance use, and a decline in motivation. Self-handicapping can be an effective strategy in the short-term, but eventually you'll suffer the consequences and end up a failure anyway.


Anatomy of Self-Handicapping

A group of Japanese researchers (Takeuchi et al., 2013) wanted to determine the neuroanatomical correlates of self-handicapping behavior, to see what sets this population apart from others. They used voxel-based morphometry (VBM) to quantify individual differences in brain anatomy across a large group of healthy students (94 men and 91 women). The participants were administered a Japanese version of the self-handicapping scale, along with assessments of self-esteem and depressive mood. The scale included questions like these (PDF):

• When I do something wrong, my first impulse is to blame circumstances.
• I always try to do my best, no matter what.
• I tend to put things off until the last moment.
• I would do a lot better if I tried harder.

Regional gray matter volumes (rGMV) were quantified in a whole-brain analysis and related to scores on the self-handicapping scale with age, sex, total brain volume, intelligence, self-esteem, and depression as covariates.

The major finding is that self-handicapping was positively correlated with rGMV in a portion of the subgenual cingulate gyrus (sgCG), or Brodmann area 25. This general area has been dubbed the "sad cingulate" by some, because it's the region targeted by deep brain stimulation for severe intractible depression by Helen Mayberg, Andres Lozano and colleagues (e.g., Riva-Posse et al. 2012).¹

Fig. 1a (adapted Takeuchi et al., 2013). Anatomical correlates of self-handicapping tendency. The region of correlation is overlaid on a single subject T1 image rGMV in sgCG was correlated with individual self-handicapping tendency. Results are shown with P < 0.05 after correction for multiple comparisons at voxel-level FWE at the whole brain level.


The extent of this correlation did not differ between males and females (see fig below). No other regions showed positive or negative correlations with self-handicapping scores. It might seem a little implausible that the size of such a circumscribed area is the only one that correlated with the tendency for self-sabotage, but there you go.

Fig. 1b (adapted Takeuchi et al., 2013). Scatter plot of the relationship between the self-handicapping scale score and rGMV values at the peak voxel (x, y, z = −5, 11, −16). The blue line represents the regression line for males, while the red line represents that for females.


A counterintuitive aspect of this result stands in contrast with previous studies of depressed individuals, who show smaller rGMV in sgCG (Drevets et al., 2008). In the present study, higher self-handicapping was correlated positively with depression symptoms and negatively with self-esteem. But remember, this was a non-clinical population of 21 yr old students, not treatment-resistant patients with severe depression. In fact, it would be interesting to follow this population longitudinally, to see if continued use of self-handicapping tactics eventually wears down mood and sgCG volumes to pathologically low levels.

After a lifetime of self-sabotage, the fill-in-the-blank answer to...

"When I do something wrong, my first impulse is to _____"

...might change from "blame circumstances" to "blame myself for being such a miserable failure." When there's no self-esteem left, why try harder? What's the point?
