Mathematics examples
Euclidean Geometry:
While it's incorrect for describing curved spaces, such as the universe's curvature (shown by general relativity), Euclidean geometry remains useful for many practical tasks like construction and architecture.
Newton’s Laws of Motion:
Despite being inaccurate for high-speed or quantum-scale objects, Newton's laws are incredibly useful in engineering and everyday applications like predicting the motion of cars or rockets.
Linear Regression:
Often oversimplifies relationships by assuming a linear correlation, yet it’s widely used in economic forecasting and trend analysis, providing useful approximations.
Bayesian Probability:
The probabilistic model assumes prior knowledge that may be incomplete or incorrect, but Bayesian reasoning remains fundamental in fields like medical diagnostics and AI algorithms for making useful predictions.

Human Sciences
Maslow’s Hierarchy of Needs:
Although criticized for its rigid structure, this model is still widely used in psychology, marketing, and education to understand motivation and behavior.
Rational Choice Theory:
Though it oversimplifies human decision-making by assuming purely rational behavior, it's still a useful model in economics for predicting market trends and consumer behavior.
Social Cognitive Theory (Bandura):
It doesn't account for all variables in human learning, but the model’s emphasis on observational learning is highly valuable for applications in behavior modification and educational strategies.
Freudian Psychoanalysis:
Criticized for being unscientific and overly deterministic, Freudian theory has nonetheless shaped our understanding of unconscious drives and therapeutic techniques that are still useful in psychotherapy.
