The ipsundrum is a central concept in Humphrey’s theory of phenomenal consciousness, referring to a self-generated conundrum or puzzle created by neural feedback loops. The term combines “ipse” (Latin for “self”) with “conundrum,” suggesting consciousness arises when the brain creates and attempts to solve puzzles about its own sensory stimulation. Humphrey proposes that feedback loops between motor and sensory brain areas, facilitated by warm-bloodedness’s enhancement of neural speed and reduced refractory periods, create these self-referential patterns. The attempt to resolve these internally generated puzzles produces the qualitative “what it’s like” character of conscious experience—the phenomenal properties that distinguish sentience from mere information processing.

Temperature elevation facilitates consciousness-enabling feedback loops through two complementary mechanisms. First, increased conduction speed (approximately 5% per degree Celsius) effectively shortens neural loops, bringing motor and sensory brain areas into closer functional contact—enabling faster, more integrated processing cycles. Second, decreased refractory periods mean neurons can fire again more quickly after initial activation, allowing participation in rapid cyclical reactivation necessary for sustained feedback. Together, these changes transform the brain from a system capable only of linear input-output processing into one supporting the complex, reverberating patterns Humphrey believes underlie phenomenal consciousness. The 22-degree temperature increase from cold-blooded ancestors more than doubled circuit speed, fundamentally altering computational possibilities.

Humphrey frames warm-bloodedness as a lucky accident because it evolved primarily to address climatic challenges—enabling survival during environmental temperature fluctuations—yet fortuitously created preconditions for sentience through unintended consequences. The adaptation wasn’t selected for consciousness but rather for geographic range expansion and activity maintenance. However, it simultaneously transformed lifestyle autonomy (fostering psychological self-conception) and optimized neural architecture (enabling feedback loops for phenomenal consciousness). This convergence of effects—lifestyle liberation plus neural enhancement—made temperature regulation what evolutionary biologists call an exaptation: a trait evolved for one purpose that proves crucial for an entirely different function. The timing, occurring independently in both mammal and bird lineages during the same climatic period, compounds the fortunate coincidence.

This article is rated Advanced level. It synthesizes concepts across neuroscience, evolutionary biology, and philosophy of mind, requiring readers to follow arguments connecting physiological mechanisms to abstract questions about consciousness. The text assumes familiarity with scientific reasoning and introduces specialized terminology (refractory periods, conduction velocity, phenomenal consciousness, attractors) while building complex causal chains from temperature regulation to subjective experience. Humphrey weaves together empirical data, theoretical speculation, and philosophical authorities (Claude Bernard, William James) to construct a novel explanatory framework. Successfully comprehending the article requires integrating multiple disciplinary perspectives and distinguishing between established facts and theoretical proposals about consciousness origins.

Blindsight, which Humphrey first demonstrated in monkeys, refers to the phenomenon where individuals with damage to primary visual cortex can respond to visual stimuli despite reporting no conscious visual experience—they process visual information without phenomenal awareness. This dissociation between information processing and subjective experience is central to understanding consciousness’s nature. Humphrey’s blindsight research suggested that conscious visual experience requires more than basic visual information processing—it needs specific neural circuits that generate the qualitative “feel” of seeing. This work laid groundwork for his later theories about phenomenal consciousness, including the warm-bloodedness hypothesis, by establishing that sentience isn’t synonymous with information processing but requires additional neural machinery creating subjective experience.

The article notes “Decades of psychological science have been devoted to right-wing authoritarian (RWA) beliefs” while “We know far less about its counterpart: Left-wing authoritarianism.” This research imbalance likely stems from multiple factors: historical focus on fascism and right-wing extremism following World War II shaped early authoritarianism research; methodological challenges in distinguishing genuine left-wing authoritarianism from progressive activism; and potential researcher bias given psychology academia’s predominantly liberal composition. The article suggests recent thought increasingly recognizes “right and left have their own distinct versions of the characteristic” rather than authoritarianism existing solely on the conservative extreme, motivating corrective research attention to LWA’s unique psychological profile and manifestations.

The article describes LWA attitudes as characterized by “expecting everyone to hold the same left-wing views, believing there is only one correct moral perspective, focusing solely on one’s own norms and boundaries, and needing rigid certainty.” These cognitive patterns translate into behavioral manifestations including bullying or shunning those with differing viewpoints, demanding political correctness from others, and pushing attitudes through censorship. The research documents “mental inflexibility” as a consistent finding, suggesting high LWA individuals struggle adapting to multiple moral frameworks or entertaining alternative perspectives. This rigidity contrasts with psychological flexibility—the capacity to recognize validity in competing viewpoints while maintaining one’s own values—resulting in absolutist thinking that treats ideological disagreement as moral failure requiring correction through social pressure.

Research reveals high LWA individuals simultaneously “See threats in multiple aspects of everyday life” and “Hold prejudiced views of African American and Jewish persons,” while also “see sexism and White privilege in everyday life, as well as holding negative views of men.” This apparent contradiction resolves when understanding LWA’s psychological mechanisms: threat hypersensitivity creates hypervigilance to certain injustices (sexism, racism against minorities) while the same rigid moral absolutism that detects these patterns also generates new prejudices against outgroups defined through ideological lenses. The article notes antihierarchical aggression shows “no relationship with altruism or social justice motivations,” suggesting concerns about discrimination may stem from grievance and threat perception rather than genuine egalitarian commitment, enabling selective moral outrage that reproduces prejudice patterns while claiming anti-prejudice stances.

This article is rated Advanced difficulty. It demands sophisticated comprehension abilities to navigate complex psychological constructs, synthesize evidence across multiple research methodologies (large-scale surveys, personality assessments, machine learning), and evaluate nuanced arguments about politically sensitive topics. Readers must understand technical terminology (authoritarianism, antihierarchical aggression, anti-conventionalism, narcissism, psychopathy), track distinctions between LWA and RWA while resisting partisan interpretation, and recognize implicit arguments about research bias and knowledge gaps. The text assumes substantial background in psychology and political science, requiring ability to distinguish between empirical findings (what research shows) and theoretical interpretations (what findings might mean), while critically evaluating claims about correlations, causation, and harm without definitive conclusions about complex phenomena.

This finding challenges assumptions that left-wing political orientations necessarily reflect compassion or egalitarian concern. The article reports antihierarchical aggression—the desire to forcefully overturn existing systems—”was also unrelated to altruism and social justice motivations” while positively correlating with narcissism and psychopathy. This suggests revolutionary impulses may stem from self-focused personality traits, resentment, or chaos-seeking rather than genuine solidarity with disadvantaged groups. The implication is profound: not all opposition to hierarchies or injustice reflects prosocial motivation; some may represent projection of personal grievances onto political targets or narcissistic desires for disruption and attention. This distinguishes authentic social justice activism rooted in empathy and fairness from authoritarian ideology that appropriates justice language while serving psychological needs for dominance, moral superiority, or retribution against perceived opponents.
