Abstract
The Kardashev scale has served for decades as a heuristic for classifying civilizations by total energy consumption. However, contemporary findings from anthropology, cultural evolution, collective intelligence research, and consciousness theory reveal that energy use is a poor proxy for cognitive advancement. This paper proposes the Consciousness Efficiency Scale (CES) as a replacement for the Kardashev scale. The CES argues that civilizational advancement should be measured by the efficiency and scope of consciousness, not the quantity of energy harvested. Evidence from evolutionary psychology, moral development, global cooperation, integrated information theory, and non-zero-sum cultural evolution supports the claim that consciousness evolves through widening circles of identity and increasingly efficient distribution of cognitive load. The CES provides a framework with five developmental levels—from survival consciousness to harmonic temporal consciousness—grounded in empirical research and theoretical synthesis. This paper outlines the CES, situates it within existing scholarship, and argues that consciousness expansion, not energy accumulation, is the true hallmark of advanced civilizations.

1. Introduction
Ever since Kardashev (1964) proposed his energy-based civilizational scale, popular science and speculative cosmology have assumed that advanced civilizations progress by harvesting increasingly vast quantities of energy—eventually dismantling planets, building Dyson structures, or consuming entire galaxies. However, this model rests on an outdated premise: that more intelligence requires more energy.
Yet humans contradict this.
The human brain consumes approximately 20 watts (Attwell & Laughlin, 2001), a figure unchanged for 200,000 years, while the functions of consciousness, abstraction, cooperation, and cultural complexity have expanded exponentially (Henrich, 2016). Civilizational progress has not required more energy; it has required greater efficiency—better information compression, wider collaboration, broader moral scope, and more integrated forms of consciousness.
This paper argues that civilization should be measured not by energy consumed, but by consciousness efficiency—the degree to which a society expands awareness, distributes cognitive load, and integrates its members into cooperative, non-zero-sum structures. This proposed Consciousness Efficiency Scale (CES) synthesizes insights from multiple fields to provide a more accurate, empirically grounded, and philosophically meaningful metric of civilizational development.

2. Critique of the Kardashev Scale
The Kardashev scale assumes a linear relationship between advancement and energy use. Modern criticisms come from at least five directions:
2.1. Efficiency Over Energy
Technological evolution demonstrates that intelligence advances by improving efficiency, not increasing raw power (Malone, 2018). A smartphone performs tasks that once required rooms full of energy-intensive machines; biological brains outperform supercomputers with orders-of-magnitude less energy.
2.2. Cultural and Cognitive Expansion Without Biological Change
Human cognition, cooperation, and moral scope have expanded dramatically without changes in human brain size or energy use (Tomasello, 2019). This indicates that software, not hardware, drives advancement.
2.3. The Moral Circle Argument
Singer (1981) and Wright (2000) show that civilizational progress correlates with expanding moral concern. This cannot be mapped onto energy consumption.
2.4. Collective Intelligence and Global Brain Models
Heylighen (2016) and Malone (2018) demonstrate that groups, networks, and systems can behave intelligently through distributed cognition—reducing individual cognitive load through cooperation and information sharing. Kardashev cannot capture these dynamics.
2.5. The Transcension Hypothesis
Smart (2012) argues that advanced civilizations move toward miniaturization, density, and computational efficiency—the opposite of the outward energy explosion Kardashev predicted.
In short, energy consumption is a poor proxy for intelligence, cooperation, efficiency, or consciousness.

3. Theoretical Foundations of Consciousness Efficiency
The CES integrates several research traditions to define consciousness not simply as awareness, but as scope + efficiency.
3.1. Expanding Moral Circles as Expanding Consciousness
Singer (1981) proposes that moral progress consists of widening circles of empathy. This aligns with anthropological data showing that human societies expanded from kin groups to tribes, states, nations, and global identities.
3.2. Cultural Evolution and Shared Intentionality
Henrich (2016) and Tomasello (2019) show that humans evolved through shared intentionality, cultural learning, and cooperation. Consciousness expanded by distributing tasks and abstractions across individuals.
3.3. Nonzero-Sum Cooperation
Wright (2000) argues that history trends toward cooperative, mutually beneficial structures—reducing the energetic cost per person.
3.4. Collective Intelligence as Cognitive Efficiency
Group intelligence reduces individual cognitive load by pooling memory, labor, knowledge, and computation (Heylighen, 2016; Malone, 2018).
3.5. Integrated Information Theory
Tononi (2004) argues consciousness correlates with the integration of information within a system—higher integration means more efficient internal structure.
Together, these findings support the central claim of the CES:
Consciousness evolves when its structure becomes more efficient and its scope becomes wider.

4. The Consciousness Efficiency Scale (CES)
C0 — Survival Consciousness
• Focus: Immediate self-preservation
• Moral circle: Self + small kin group
• Cognition: Reactive, low abstraction
• Cooperation: Minimal
• Efficiency: Low; high personal energy cost
C1 — Tribal Consciousness
• Focus: In-group solidarity
• Moral circle: Tribe
• Cognition: Shared myth, identity, and ritual
• Cooperation: Coordinated, but limited
• Efficiency: Moderate; energy distributed across dozens–hundreds
C2 — Cultural Consciousness
• Focus: Institutions, laws, writing
• Moral circle: City or nation
• Cognition: Symbol manipulation, long-term planning
• Cooperation: Large-scale
• Efficiency: High; society reduces individual cognitive burden
C3 — Universal Human Consciousness
• Focus: All humans as part of moral circle
• Cognition: Scientific rationality, global knowledge networks
• Cooperation: Planetary
• Efficiency: Very high; problems solved through collective intelligence
C4 — Interbeing Consciousness
• Focus: Humans + animals + ecosystems + artificial minds + future generations
• Cognition: Systems thinking, long time horizons
• Cooperation: Multi-species and multi-system
• Efficiency: Civilizational optimization across biological and artificial agents
C5 — Harmonic or Temporal Consciousness (Speculative)
• Focus: Consciousness integrated with deeper structures of reality (frequency, temporality, informational fields)
• Cognition: Multi-scale, reflective, and meta-systemic
• Cooperation: Between forms of intelligence across time or dimensions
• Efficiency: Near-maximal; consciousness uses minimal energy for maximal effect

5. Implications of the CES
5.1. A New Interpretation of Civilizational Progress
Progress is defined not by energy capture but by the expansion of conscious scope and the reduction of per-person cognitive and energetic burden.
5.2. Why Advanced Civilizations May Be Invisible
If civilizations optimize inward rather than outward (Smart, 2012), they may produce minimal waste heat and no megastructures—explaining the Fermi paradox.
5.3. A Better Measure of Humanity’s Current Trajectory
Humanity is transitioning from C2 to C3, and in some domains toward C4. Global cooperation, concern for distant populations, and emerging AI governance are early indicators.
5.4. Alignment With Sustainable and Moral Futures
The CES naturally rewards cooperation, efficiency, solidarity, and ethical expansion—qualities associated with long-term survival.

6. Conclusion
A civilization’s true advancement is measured not by how much energy it consumes, but by how efficiently it organizes consciousness—how widely its moral circle extends, how effectively it distributes cognitive load, and how deeply it integrates information. The Consciousness Efficiency Scale provides a more accurate, human-centered, and scientifically grounded model of civilizational development than the outdated Kardashev paradigm. As humanity’s consciousness continues to evolve, the CES may offer a roadmap for understanding not only our past and future, but the possible trajectories of intelligent life throughout the universe.
