It is not 'oversimplification', but pointing out the traps and pitfalls of empirical validation. If you gain new hypotheses in the process of validating and falsifying your old ones, you need a second, independent study to validate the new ones. You anyway always run the danger that the result you found is a random artefact of your study participant group. If you validate the new insights with the same group, this risk becomes uncontrollable (e.g., confidence intervals become meaningless in such a setting).
