It has been shown that under great pressure, most people will revert to:

Under conditions of high stress or pressure, individuals often revert to behaviors that are familiar and well-practiced, which are typically described as habits. This response is rooted in the brain's instinct to rely on established patterns of behavior when faced with overwhelming situations.

When faced with anxiety or danger, higher cognitive functions may be impaired, making it difficult for people to think critically or make rational decisions. Instead, they tend to fall back on actions they have previously learned and rehearsed, which can include physical skills or procedures related to their training. This reliance on habitual responses can be particularly critical in emergency situations, where quick and automatic actions may prevent harm or assist in managing the crisis effectively.

While panic, common sense, and following orders are all responses that people may exhibit under pressure, they do not capture the instinctual reversion to learned behaviors as accurately as habits do. Panic can lead to confusion and inaction, common sense might be stifled under stress, and following orders typically requires a level of calmness and clarity that may not prevail in high-stress situations. Therefore, reverting to habit is often the most natural and immediate response when under great pressure.
