Capacity to act
Still being able to decide and make a difference under pressure, instead of freezing or merely reacting.
The capacity to act is the state in which a person can still decide consciously and act purposefully under pressure, instead of freezing, avoiding, or merely reacting. Research speaks of agency: the experience of being the author of your own actions. The capacity to act is what separates strain from overwhelm. It is the goal of mental strength.

The state in which you choose instead of being driven.
Not activism. Whoever becomes frantic under pressure is not acting but reacting.
It is the measure by which mental strength shows itself in the moment of strain.
Origin and research
Albert Bandura described agency in 2001 as the core of human action: the ability to act intentionally, plan ahead, regulate one's own behavior, and reflect on oneself. All four components are at stake under pressure. Stress narrows attention, shortens the planning horizon, and weakens self-regulation.
The capacity to act is therefore a reserve that shrinks under strain and returns with recovery. Whoever wants to preserve it works on what happens between the strains.
For high performers
The capacity to act is rarely lost all at once. It fades in stages: first decisions get postponed, then delegated, then avoided. From outside it looks like overload. From inside it feels as if there is simply a lot going on right now.
The first step back to the capacity to act is not the big decision but the smallest one you can still make today. Whoever decides one thing regains the experience of being the author. That experience is the currency in which the capacity to act is paid.
Distinctions
vs. Self-efficacy
Self-efficacy is the expectation of being able to make a difference. The capacity to act is the state in which you actually do.
vs. Locus of control
Locus of control is the basic assumption that acting changes anything at all. The capacity to act is the acting itself.
vs. Activism
Activism is movement without decision. The capacity to act is decision, even when it means holding still.
Frequently asked questions
What does capacity to act under pressure mean?
That in a stressful situation you still consciously choose what you do instead of reacting automatically. The criterion is whether you decide. The decision to wait is also the capacity to act.
Why do I lose the capacity to act under stress?
Because stress narrows attention and shortens the planning horizon. The brain switches over to reaction. That is biologically sensible in acute danger and counterproductive under sustained pressure at work.
How do I get my capacity to act back?
Through a small decision that you actually make. The next one in line. Every conscious decision restores the experience of being the author of your own actions. From that experience the next one grows.
