Consciousness: what we know, what we don’t, and why it’s hard
Bloom explains that psychology and neuroscience can describe many correlates of conscious experience, but the core mystery—how physical brains generate subjective experience—remains unsolved. The conversation frames consciousness as both a scientific and philosophical challenge, not something with a settled evolutionary “purpose.”
- •We don’t know why consciousness exists (vs. functional ‘zombies’) or how the brain produces experience
- •Distinction between understanding mechanisms vs. explaining subjective ‘feel’
- •Consciousness research is real, but the biggest questions still elude current science
- •Evolutionary stories may not straightforwardly explain phenomenology
- 1:59 – 7:41
Access vs. phenomenological consciousness, epiphenomena, and individual differences
They separate ‘access consciousness’ (information available for reasoning/report) from ‘phenomenological consciousness’ (what it feels like). Bloom explores whether subjective feel could be an epiphenomenon and discusses striking variability in inner experience, from synesthesia to aphantasia and inner narration.
- •Access consciousness supports reasoning, language, and social understanding
- •Phenomenological consciousness (‘the feel’) is the deeper mystery
- •Epiphenomenal traits can arise as byproducts without direct adaptive function
- •Examples of variation: synesthesia, aphantasia, internal narrator, differences in pain/color experience
- 7:41 – 10:09
Memory isn’t a recording: loss, reconstruction, and false confidence
Bloom pushes back on the idea that memory is like an iPhone recording stored permanently and retrievable later. He describes memory as selective and reconstructive, which makes it useful but also deeply fallible—especially when confidence is mistaken for accuracy.
- •Most experience is never encoded; much is lost quickly
- •Remembering is partly reconstruction, influenced by cues and suggestions
- •Leading questions can generate false memories
- •Flashbulb memories (e.g., 9/11) drift dramatically over time despite high confidence
- 10:09 – 11:55
Attention as the bottleneck: the Invisible Gorilla and practical memory advice
The conversation connects memory failure to attention limits, using the ‘Invisible Gorilla’ study to show inattentional blindness. Bloom offers practical guidance: if you want to remember something, you must attend to it; expertise often means learning where to look.
- •Inattentional blindness: missing salient events when attention is elsewhere
- •Without attention, information may be ‘gone’ within seconds, not months
- •Training builds expertise by teaching what cues matter (radiologists, air-traffic controllers)
- •Memory techniques exist (mnemonics), but they don’t fix everyday absent-mindedness
- 11:55 – 15:47
Eyewitness testimony, cross-race effects, and ‘training data’ for perception
Bloom explains why eyewitness confidence is a poor indicator of truth and why recognition errors are common. They discuss the cross-race effect as largely an expertise/familiarity issue—experience tunes discrimination, much like ‘training data’ in AI.
- •Juries overvalue confident testimony; errors can be revealed by DNA/exonerations
- •Cross-race recognition is often weaker due to less exposure, not inherent hostility
- •Perceptual expertise improves with repeated need to distinguish similar instances
- •Baby face/looking preferences can reflect familiarity rather than innate racism
- 15:47 – 25:54
Tribalism vs. racism: what babies actually prefer (language over skin color)
Bloom argues ‘tribalism’ is a better frame than ‘racism’ for early social preferences. Evidence suggests young children track coalition cues like language and accent strongly, while skin color becomes socially meaningful later depending on the culture’s fault lines.
- •Babies/toddlers show strong social preferences early, but not primarily by skin color
- •Language and accent are powerful ‘us vs. them’ cues with plausible evolutionary roots
- •Preferences reflect familiarity and local environment rather than fixed racial bias
- •Adults reliably encode sex/gender, age, and race—though race is more culturally contingent
- 25:54 – 29:20
Freud in 2023: mostly wrong, but the unconscious matters
Bloom dismisses most specific Freudian stage theories while crediting Freud’s enduring contribution: the idea of a dynamic unconscious shaping choices and narratives. They connect this to political/moral psychology and the limits of introspection.
- •Freud’s developmental/sexual stage claims largely haven’t held up
- •Freud’s key legacy: unconscious motives influence behavior and self-explanations
- •People often confabulate coherent stories rather than report true causes
- •Understanding unconscious drivers matters for domains like voting and moral judgment
- 29:20 – 33:36
Self-deception and the strategic unconscious (Trivers’ idea)
They explore why some mental processes might be unconscious beyond mere capacity limits—because self-deception can help deceive others. Examples include signaling toughness in conflict and wholehearted commitment in love, where doubt can undermine credibility.
- •Unconsciousness may support social deception by hiding ulterior motives
- •Believing your own narrative can make your signals more convincing
- •Applications: conflict displays, romantic commitment, optimism about marriage success
- •Separating belief from reality becomes tricky in emotions like love
- 33:36 – 38:56
Intuition vs deliberation: Kahneman’s systems and when ‘thinking’ backfires
Bloom frames intuition as fast ‘System 1’ and deliberation as slow ‘System 2,’ arguing each has contexts where it excels. They discuss situations where analysis impairs skilled performance (sports, social fluency) and where ‘reason’ turns into post-hoc lawyering.
- •System 1: quick, heuristic, sometimes biased; System 2: reflective, analytic
- •Deliberation is often better for high-stakes life decisions when time allows
- •Overthinking can disrupt expert motor/social performance
- •Rationalization risk: deliberation can become ‘lawyer’ defending gut reactions
- 38:56 – 45:17
Why behaviorism fell out of favor—and what it still explains (social media, reinforcement)
Bloom critiques Skinner’s strict refusal to invoke internal mental states, arguing modern cognitive science and AI show the need for ‘machinery inside.’ Yet he acknowledges behaviorist insights like intermittent reinforcement, especially in addiction-design patterns such as social media.
- •Behaviorism’s core limitation: ignoring beliefs, desires, memory, internal computation
- •Computers/AI illustrate why internal representations are essential for explaining intelligence
- •Intermittent reinforcement sustains behavior powerfully (slot machines, social media feeds)
- •Rewards can undermine intrinsic motivation; humans reflect on meanings, not just reinforcements
- 45:17 – 47:27
Perverse desires: wanting the ‘wrong’ thing because it’s wrong
Bloom introduces his interest in perversity—actions motivated by the transgression itself rather than by external rewards. He shares classic and modern anecdotes (Augustine’s pears; finger in a friend’s ice cream) to illustrate non-Skinnerian motivations.
- •Some behaviors are driven by the lure of wrongdoing, not reinforcement
- •Augustine’s theft example: no hunger, no gain—just transgression
- •Everyday perversity stories reveal motivations beyond conditioning models
- •Sets up a broader project on why ‘badness’ can be intrinsically attractive
- 47:27 – 51:52
What babies (and animals) know: core knowledge, instincts, and helplessness
Bloom describes developmental psychology findings that infants possess surprisingly rich ‘core knowledge’ about physics and social agents. They contrast humans’ long helpless childhood with animals’ varying degrees of innateness, and discuss instincts vs pre-wired understanding.
- •Infants show early understanding of object permanence, gravity, contact causality
- •Early social expectations: helping/harming predicts future affiliation/avoidance
- •Blank-slate views are undermined; some cognition appears pre-specified by evolution
- •Animals show mixes of innate behavior and learning (e.g., bird song); humans have few fixed behaviors but rich early intuitions
- 51:52 – 57:07
Language and thought: expression, reflection, and why language doesn’t dictate cognition
They tackle the idea that language limits thought, distinguishing true links (communication, structuring) from strong linguistic determinism. Bloom argues languages differ in form but do not create fundamentally different minds; thoughts are typically less ambiguous than words.
- •Language conveys thoughts and can reflect conceptual structure (space-time metaphors)
- •Strong Sapir-Whorf claims (language determines thinking) usually fail empirically
- •People feel they ‘think in words,’ but thoughts often outrun linguistic ambiguity
- •Bilingual mode shifts can cue memories/affect without changing core cognitive capacities
- 57:07 – 1:02:33
Sex differences in psychology: robust averages, big overlap, and culture interactions
Bloom discusses widely replicated sex differences—especially in aggression/risk-taking and nurturance—while emphasizing bell-curve overlap and cultural modulation. They explore how egalitarian contexts can sometimes magnify differences by allowing freer preference expression.
- •Largest difference: average heterosexual attraction patterns (with many exceptions)
- •Common cross-cultural findings: men more violent/risk-taking; women more nurturing
- •Bell-curve framing: average differences coexist with extensive individual overlap
- •Culture shifts baselines (e.g., desired number of partners) while preserving direction of sex effects
- 1:02:33 – 1:12:55
Attachment theory, heritability, and why parenting effects are often overstated
Bloom argues attachment theory isn’t entirely false but is often overextended, especially when used to claim parenting strongly determines adult outcomes. They pivot to behavioral genetics: many traits are substantially heritable, and non-home environments can matter more than parenting style.
- •Attachment styles exist, but strong causal claims are questionable
- •Parent-child similarity can reflect shared genes rather than parenting effects
- •Adoption and genetics research suggests limited long-run parenting impact on personality/intelligence
- •Practical lens: focus on fit between self, relationships, and work rather than trying to remake temperament
- 1:12:55 – 1:19:37
Reforming education and public understanding around genetics, selection, and future tech
Chris argues heritability education is a major public ‘missing lever,’ and Bloom agrees while noting political sensitivities. They discuss embryo selection, donor gametes, and how real-world choices reveal people’s implicit belief that traits are partly inherited.
- •Behavioral genetics is politicized but discussable compassionately and rigorously
- •Many laypeople intuit heritability reasonably well when asked concretely
- •Reproductive tech (donors/embryo selection) makes genetic influence harder to ignore
- •Separating attraction from procreation can shift trait preferences (e.g., dominance vs kindness)
- 1:19:37 – 1:25:34
Can psychology tell us how to live? Happiness vs meaning, kids, and indirect routes to wellbeing
Bloom argues the ‘good life’ is ultimately philosophical, but psychology can inform how to achieve chosen goals. They discuss research on whether children increase happiness (it depends on context) and the broader idea that directly chasing happiness can reduce it, while meaning and values often help.
- •Good life is a moral/philosophical question; psychology helps with means, not ends
- •Kids and happiness: effects vary by gender, age, and social supports like childcare
- •Meaning/importance can diverge from day-to-day pleasure
- •Overvaluing happiness can correlate with lower happiness; indirect pursuit may work better
- 1:25:34 – 1:27:45
What psychology might unravel next: AI as a mirror and stalled progress in clinical science
Bloom predicts AI will reshape psychology by enabling comparisons between human intuitions and statistical learning systems. He also highlights clinical psychology as an area ripe for breakthroughs, citing limited major progress in recent decades and emerging interest in psychedelics, meditation, and neuro-interventions.
- •Using models like ChatGPT to contrast machine vs human judgments and intuitions
- •AI’s rise may transform experimental design and theory-building
- •Clinical psychology has seen fewer ‘big’ leaps; potential change may be coming
- •New frontiers: psychedelics, mindfulness, and brain stimulation techniques
- 1:27:45 – 1:28:39
