Psychological flexibility
Being able to switch perspectives and strategies when the situation demands it. Also called mental flexibility.
Psychological flexibility is the ability to adapt thinking and behavior to a changed situation, even when the previous strategy has served well. In everyday language it is often called mental flexibility. It involves three things: recognizing that the situation has changed, allowing alternative readings, and actually changing behavior. Its opposite is rigidity.

The ability to change course without losing the destination.
Not arbitrariness and not bending with every wind. The path is flexible, not the goal.
Research ranks it among the strongest predictors of psychological health overall.
Origin and research
Todd Kashdan and Jonathan Rottenberg reviewed the research on psychological flexibility in 2010 and reached a clear conclusion: it is a central component of psychological health, often more important than any single skill. People with high flexibility adapt their strategy to the context; people with low flexibility apply the same strategy everywhere, including where it does harm.
The term comes from acceptance and commitment research (Hayes), where it describes the ability to stay in contact with the present moment and to align behavior with one's values, even when unpleasant feelings come with it.
For high performers
Success breeds rigidity. Whoever won with a strategy uses it again next time, and the time after that even when the situation is different. The strategy has proven itself, so the context must be wrong. This is how leaders who solve everything with a hammer come about.
Flexibility shows not in giving in, but in the question of whether the situation is still the same as at the last success. Whoever asks that question regularly stays agile. Whoever never asks it is eventually corrected by reality, usually at a higher price than necessary.
Distinctions
vs. Rigidity
Rigidity is the direct opposite: holding on to patterns of thought and behavior even when they no longer fit.
vs. Stubbornness vs. consistency
Consistency holds on to the goal and stays flexible about the path. Stubbornness holds on to the path even when the goal is lost.
vs. Cognitive reappraisal
Reappraisal is a single change of perspective. Flexibility is the underlying ability to make one.
Frequently asked questions
Is psychological flexibility the same as mental flexibility?
In everyday use, yes. Psychological flexibility is the scientific term from acceptance and commitment research. Mental flexibility is the everyday version. Both mean the ability to adapt thinking and action to changed conditions.
Can psychological flexibility be trained?
Yes. The most effective lever is to formulate, in decision situations, a second reading and a second strategy before acting. The point is the choice itself, not its outcome.
Isn't flexibility the opposite of steadfastness?
No. Steadfastness concerns values and goals, flexibility concerns paths and strategies. Whoever confuses the two becomes either rigid in method or arbitrary in aim. The combination of a fixed goal and a flexible path is the core of mental strength.
