Content: An individual's behaviour is not always in alignment with their intentions (termed a value-action gap ). It is common knowledge that humans are not fully rational beings; that is, people will often do something that is not in their own self-interest, even when they are aware that their actions are not in their best interest. As an example, when hungry, people who diet often underestimate their ability to lose weight, and their intentions to eat healthy can be temporarily weakened until they are satiated. Nobel Laureate Daniel Kahneman describes two distinct systems for processing information as to why people sometimes act against their own self-interest: System 1 is fast, automatic, and highly susceptible to environmental influences; System 2 processing is slow, reflective, and takes into account explicit goals and intentions. When situations are overly complex or overwhelming for an individual's cognitive capacity, or when an individual is faced with time-constraints or other pressures, System 1 processing takes over decision-making. System 1 processing relies on various judgmental heuristics to make decisions, resulting in faster decisions. Unfortunately, this can also lead to sub-optimal decisions.
