What constitutes the naturalness?
What is it in nature that makes attending to it effortless?

Naturalness judgements are less affected by subjects´ background
Consensus for a fractal dimension around 1.3 as most natural, and most preferred
Waves and clouds have a dimension of 1.3
Fractal scenes with a dimension 1.3 - 1.5 have shown a damping effect on stress.

Can fractal properties help define general concepts like complexity and coherence?
Can fractal properties, like self similarity between scales, explain why attending to natural environments is effortless?

The fractal dimension 1.3 is of particular importance to perceived naturalness.
….and possibly also to positive psychological and physiological responses?
