Why is low ecological validity bad?

Why is ecological validity important in research?
When research has high ecological validity it means that behaviour recorded within the research can be applied to everyday life. This means that the results are more useful.
What usually happens to internal validity as ecological validity increases?
Raising external validity often results in a lower level of internal validity. … The more you try to raise ecological validity, the less control you will have over confounding variables in your experimental setting.
What affects ecological validity?
Stimuli under examination
Evaluating ecological validity requires comparing stimuli used during testing to those encountered in daily life. … Such studies often return results with low ecological validity. On the other hand, naturally occurring stimuli (such as images and sounds) increase ecological validity.
What is ecological validity in educational research?
