8.2.2026 – Cognitive filters don’t determine which cultural experiments gain acceptance

Cognitive filters don’t determine which cultural experiments gain acceptance. Filters influence which are selected. The same can be said for the role of incumbent elites in the selection process.

I think that’s an important refinement. In evolutionary theory, selection is distinct from variation. Earlier I blurred those two processes.

A cleaner formulation would be:

Cognitive filters do not determine which cultural experiments are generated. They influence which experiments are selected, retained, and transmitted.

Likewise:

Incumbent elites do not necessarily generate institutional innovation. They disproportionately influence which institutional innovations are selected, resourced, legitimized, implemented, and preserved.

This produces a much cleaner evolutionary architecture.

This also suggests that your theory has three distinct stages of selection, each operating at a different level.

1. Psychological selection

Cognitive filters influence which innovations people

• pay attention to,
• understand,
• trust,
• support,
• imitate.

They bias the selection of cultural variants, not their creation.

2. Institutional selection

Incumbent elites, together with existing institutions, influence which variants receive

• funding,
• legal authority,
• organizational support,
• media visibility,
• political legitimacy,
• implementation.

Again, this is principally a selection process rather than one of invention.

3. Environmental selection

Reality then becomes the ultimate selector.

Institutions are tested by

• ecological sustainability,
• economic performance,
• military competition,
• demographic success,
• legitimacy,
• resilience.

Some survive.

Others disappear.

I would even sharpen the central proposition:

Human cultural evolution is fundamentally a process of differential selection acting on institutional variation. Cognitive filters shape psychological selection. Incumbent elites shape institutional selection. Environmental and societal outcomes shape long-term evolutionary selection.

That has a pleasing symmetry.

In fact, I think this may become one of the defining features of your theory. Much of the literature on cultural evolution focuses on innovation—where new ideas come from. Your project increasingly focuses on selection—why some innovations become institutions while others disappear.

That shift is important because evolutionary theory is fundamentally a theory of selection acting on variation, not simply a theory of innovation. It also gives you a clear causal sequence:

1. Variation — societies continually generate new ideas and institutional experiments.
2. Psychological selection — cognitive filters influence which experiments gain social support.
3. Institutional selection — incumbent elites and existing institutions determine which supported experiments are adopted and scaled.
4. Environmental selection — long-term ecological, economic, and social performance determines which institutions ultimately persist.

This formulation also avoids attributing excessive agency to either cognition or elites. Neither creates the evolutionary process; both act as selection mechanisms operating on a much larger pool of cultural variation. That is a more faithful analogy to biological evolution and, I think, a stronger foundation for your developing theory.
