The Left–Right Political Spectrum

Do you know what's behind the political spectrum usually described as a left-right continuum? For example, could it be explained in terms of Edelman's value systems: different inherited values weight the categorisation of experience along different paths?

Yes, the political spectrum, often described as a left-right continuum, can indeed be explained in terms of Edelman’s value systems, where different inherited and learned value systems influence how individuals categorise and prioritise experience. This explanation offers a biological and adaptive grounding to political ideologies.

Edelman’s Value Systems and Categorisation

In Edelman’s theory, value systems are neural mechanisms that evolved to guide behaviour in response to environmental challenges and opportunities. These systems assign adaptive significance to stimuli, shaping perception, learning, and decision-making. Over time, these systems influence how individuals categorise and respond to their experiences. When applied to political thought:

1. Inherited Value Systems:

   • These reflect deep evolutionary pressures and guide fundamental survival strategies. For example, a tendency towards cooperation might align with collective, egalitarian values (often associated with the left), while a focus on competition and hierarchy might align with individualistic, conservative values (often associated with the right).

2. Learned Value Systems:

   • Social and cultural learning influences how inherited tendencies are expressed. For example, an inherited drive for fairness might lead to different political interpretations depending on cultural norms—such as advocating for wealth redistribution on the left or for equality of opportunity on the right.

Categorisation of Experience

Political ideologies emerge from the interaction between inherited value systems and how experience is categorised. The paths taken by categorisation reflect different weightings of value systems:

1. The Left:

   • Higher Weight on Social and Cooperative Values:
     The left often emphasises empathy, equity, and collective welfare. These reflect inherited tendencies toward group cohesion and mutual support, prioritised in certain contexts like managing shared resources or addressing inequality.
   • Categorisation of Experience:
     Issues are framed in terms of systemic dynamics (e.g., class struggle, systemic oppression). The left may categorise wealth disparity or environmental degradation as problems requiring collective action.

2. The Right:

   • Higher Weight on Stability and Hierarchical Values:
     The right often prioritises tradition, order, and individual responsibility. These values emerge from inherited mechanisms that favour preserving resources, maintaining boundaries, and asserting individual dominance in competitive scenarios.
   • Categorisation of Experience:
     Issues are framed in terms of individual accountability and respect for established norms (e.g., law and order, family values). Hierarchical distinctions are often seen as necessary or inevitable.

Why Is the Spectrum a Continuum?

The left-right spectrum arises because political ideologies represent different balances of these inherited value systems, weighted differently depending on environmental and social contexts. The continuum reflects the fact that most people blend these values rather than adhere to extremes.

• Left and Right as Complementary Adaptive Strategies:
  From an evolutionary perspective, both cooperation (left) and competition (right) have survival value, depending on context. In stable environments, hierarchical systems may ensure stability; in crises, cooperative strategies may dominate.

• Neurodiversity and Ideological Diversity:
  Individuals differ in how their neural value systems are weighted, leading to diverse political perspectives within any given population. This diversity can enhance adaptability at the societal level.

Examples of Categorisation Along Political Lines

1. Economic Inequality:
   • Left: Categorised as systemic exploitation requiring redistribution.
   • Right: Categorised as a natural outcome of individual effort and risk-taking.
2. Immigration:
   • Left: Categorised as an opportunity for mutual enrichment and humanitarian action.
   • Right: Categorised as a potential threat to cultural stability and resource allocation.

Evolving Political Categorisations

Changes in the political landscape can reflect shifts in the collective weighting of these value systems due to cultural evolution, technological change, or environmental pressures. For example:

• Climate change has made environmental concerns a higher priority across the spectrum, although solutions are categorised differently (e.g., systemic action on the left vs. market-driven innovation on the right).

Implications

Understanding political ideologies through the lens of Edelman’s value systems provides a biological and cognitive basis for ideological diversity. It suggests that political conflict often arises not from fundamental incompatibilities but from differences in how experiences are categorised based on weighted values.
