Applied Behavior Analysis Technician (ABAT) Practice Test

Which principle emphasizes the need to rule out simple explanations before considering complex ones?

1. Parsimony

2. Prediction

3. Replication

4. Determinism

The correct answer is: Parsimony

The principle that emphasizes the need to rule out simpler explanations before considering more complex ones is known as parsimony. This principle is often encapsulated in the axiom "entities should not be multiplied beyond necessity." In practice, it means that when trying to understand behavior, practitioners should first consider the most straightforward explanations before delving into more intricate theories or hypotheses. This aligns with the scientific approach of favoring simple solutions unless evidence suggests that more complicated explanations are necessary. By adhering to this principle, practitioners save time and resources, ensuring that interventions are based on well-founded reasoning. In the field of applied behavior analysis, this encourages a systematic approach to understanding behavior that is efficient and focused. This is particularly important in guiding decisions about behaviors and interventions that impact individuals, as it promotes clarity and practical solutions.
