Human performance can be affected by many factors such as age, state of mind, physical health, attitude, emotions, propensity for certain common mistakes, errors and cognitive biases, etc. Human reliability is very important due to the contributions of humans to the resilience of systems and to possible adverse consequences of human errors or oversights, especially when the human is a crucial part of the large socio-technical systems as is common today. User-centered design and error-tolerant design are just two of many terms used to describe efforts to make technology better suited to operation by humans. People tend to overestimate their ability to maintain control when they are doing work.The common characteristics of human nature addressed below are especially accentuated when work is performed in a complex work environment. Stress The problem with stress is that it can accumulate and overpower a person, thus becomingdetrimental to performance. Avoidance of Mental Strain Humans are reluctant to engage in lengthy concentrated thinking,as it requires high levels of attention for extended periods.
