The phrase “leap of faith” is not a scientific term and comes from philosophy (S. Kierkegaard and his followers). Nevertheless, psychology has studied in detail the internal processes that usually underlie this expression: trust in oneself and the world, willingness to act under conditions of uncertainty, optimism, hope, and religious or spiritual faith.
Research by Albert Bandura shows that a person’s belief in their own ability to cope with tasks (self-efficacy) is directly related to whether they will try something new, how much effort they will invest, and how long they will persist in the face of difficulties. PubMed+1
The work of C. R. Snyder and colleagues on hope theory demonstrates that the feeling “I want this and I will find a way” is associated with greater persistence, better academic and professional achievement, and higher resilience to stress. ou.edu+1
Studies of optimism (Scheier & Carver) show that a stable expectation of favourable outcomes is linked to better physical and mental health, more active coping, and a greater tendency to move forward even when there are no guarantees. ResearchGate+2PubMed+2
There are also major reviews on religious faith and spirituality as ways of coping with stress, illness, and uncertainty. They show that for many people, faith and spiritual experience help to maintain hope and meaning in difficult life situations. PubMed+2PMC+2
Thus, in scientific terms, a “leap of faith” can be described as a combination of
– high self-efficacy and hope;
– willingness to accept uncertainty and risk;
– trust in one’s own path (sometimes within a religious or spiritual framework).
