Which of the following is one of the seven attitudes of science?

• A. Philosophic Doubt
• B. Behavioral
• C. Theoretical
• D. Applied

Answer: (D)

Philosophic doubt is an attitude of science that means maintaining healthy skepticism, questioning claims, and demanding evidence before accepting explanations. This mindset keeps science adaptable and self-correcting, since ideas must be tested and can be revised in light of new data. In behavior analysis and science more broadly, it sits alongside other guiding attitudes like empiricism, determinism, experimentation, replication, parsimony, and societal relevance, shaping how we gather and evaluate evidence. The option describing practical focus—Applied—captures a domain of work rather than an attitude, so it doesn’t fit as an attitude of science.
