Gua-Rino Theorem

The Gua-Rino Theorem is a philosophical and psychological theory developed by conceptual artist Andrea Gua Nong Son Rinh and philosopher and mathematician Rino Perlato. It proposes a conceptual model to explain how the human mind assigns subjective numerical values, on a scale of 1 to 10, to any element of lived experience: objects, people, concepts, events, emotions and even the idea of nothingness.

Enunciation

Any subjective evaluation on a numerical scale is a fictitious synthesis of three cognitive forces: emotional memory (M), symbolic context pressure (C), and the illusion of internal consistency (I), such that:

V = f(M, C, I) ± ε

where V is the assigned value, f is a nonlinear subjective weighting function, and ε is the temporary irrational fluctuation.

Theoretical foundations

The theorem is based on the idea that the very act of judging is a compromise between emotional impulse, influence of social context and internal desire for narrative coherence. In this sense, the numerical scale becomes a “symbolic prosthesis of emotional judgment.”

According to Perlato:

«Each number is a compromise between emotion, external pressure and the desire to appear consistent.»

Universal Extension

The theorem applies to every possible entity that can be experienced or imagined. The authors argue that there is nothing that the human mind cannot, at some point, evaluate numerically, even unconsciously. For example:

• A loved one may receive a “9” in a moment of happiness, but a “6.5” during a conflict.
• A political idea may be worth “10” to those who perceive it as consistent, but “2” in case of personal dissonance.
• The very concept of self can fluctuate under the domain of ε.

Supplementary formulas

Instantaneous self-assessment

The self-assessment of a subject at a given time t is expressed by the formula:

A(t) = f(Mₛ, Cₛ, Iₛ) ± εₛ(t)

where subscripts "s" indicate that the factors are referring to the subject itself.

Cumulative social evaluation (meta-judgment)

The arithmetic mean of individual evaluations is used to represent a collective evaluation-as in surveys, online reviews, or rating systems:

V̅ = ∑Vᵢ / n

where V̅ is the average rating, used for example in social or surveys. However, according to Perlato:

«Grade average is not the truth. It is only the shared illusion of a sum of illusions.»
