A paradigm is the prevailing and widely accepted way of thinking or framework. More narrowly, a paradigm can also refer to the central theory or direction of a scientific discipline or art.
New paradigms replace old theories and transform science, technology, and human life. For example, Charles Darwin's theory of evolution or the discovery of DNA revolutionised the field of biology. Technological advancements such as electric motors, social media, mobile phones, or streaming services have disrupted their respective industries and impacted all our daily lives.
Changing a paradigm is not easy or quick because there are structures, power dynamics, and societal relationships entrenched around old paradigms.
Sustainability transformation is one example of an ongoing change in paradigms.

Systems thinking helps to understand the functioning of complex systems as a whole and the interactions between their parts. It helps to perceive structures and find leverage points for solving complex and ambiguous problems.
Wicked problems, such as climate change, arise from outdated systems and ways of thinking and thus require new approaches, expertise, and cross-organisational models of action.
As Albert Einstein said, 'We cannot solve problems with the same thinking we used when we created them.'
