Systems Thinking is the ability to see the consequences of our actions. Also, it involves the understanding of relationships and interrelations between subjects within a system in any situation, to have better knowledge about how things unfold over time. Usually, a human being reacts to immediate circumstances, but it is more difficult to analyze how our past actions and decisions may influence a specific situation. This study introduces the reasons why system thinking is an essential tool to approach modern social systems and explain the foundations of Systems Thinking and how they collaborate to design strategies and solutions to induce changes in a complex and chaotic system. We suggest that this methodology is essential to minimize the negative impact of the information technologies on society.
