What is PeopleAnalyst?

PeopleAnalyst is the front door for people-analytics research: 205+ works indexed and profiled, 40+ citation-grade findings extracted, and peer-reviewed behavioral science translated from academic to actionable — the missing manual for the people analytics you always meant to do.

What is people analytics?

People analytics is not a dashboard. It is behavioral science and statistical inference applied to workforce decisions — a discipline with its own methodology, spanning measurement, organizational design, talent, leadership, and analytics craft.

Why does AI in HR need measurement science?

AI is being deployed in high-stakes people decisions — hiring, performance, attrition — without the measurement science to evaluate whether it works or whom it harms. Construct validity, effect sizes, and criterion validity are the vocabulary for asking an AI vendor the right questions.

How is the research made accessible?

The evidence is indexed and searchable: 205+ works, 40+ citation-grade insight cards, and 8 research arcs, so the right finding reaches the right decision at the right time.

What separates good people measurement from assertion?

Good measurement has a method: construct validity, reliability, and effect-size interpretation are not optional — they are what separates evidence from assertion.

The Savage Mind

In a sentence

Claude Lévi-Strauss argues that 'primitive' thought is not a rudimentary stage of intellectual development but a parallel, equally complex and logical system for ordering the world, which he terms the 'science of the concrete'.

Challenging the long-held Western assumption that 'primitive' thought is illogical, irrational, and purely utilitarian, 'The Savage Mind' demonstrates that so-called 'savage' peoples possess an incredibly detailed and systematic knowledge of their environment, driven by an intellectual 'thirst for objective knowledge' rather than just immediate needs. Lévi-Strauss introduces the concept of the 'bricoleur' to describe this mode of thought, which uses a finite set of pre-existing elements—signs, myths, materials—to create new structures and meanings, much like a handyman uses whatever tools are at hand. This 'science of the concrete' operates through analogies and correspondences, creating complex classificatory systems (such as totemism) that are homologous to, but different from, modern abstract science. The book argues that these two modes of thought are not sequential stages of development but parallel paths to knowledge, one operating at the level of sensible qualities and the other at a remove from them, revealing the fundamental unity of the human mind.

The model

This model outlines Lévi-Strauss's theory of 'savage thought' as a structured, logical system. It posits that a universal demand for order, operating on detailed observations of the sensible world and a finite cultural repertoire, gives rise to a 'science of the concrete'. This mode of thought, acting as a form of 'intellectual bricolage' using a logic of oppositions, produces complex classificatory systems that render the universe intelligible, articulate social structure, and allow for conceptual translation between different cultural domains.

Demand for Orderpsychological state

The fundamental and universal human intellectual requirement to reduce chaos by assigning every creature, object, or feature to a place within a class, based on the postulate that nature itself is orderly.

Observation of the Sensible Worldbehavioral pattern

The sustained, attentive, and detailed examination of the biological and physical environment, driven by a desire for objective knowledge for its own sake, encompassing minute differences between species and varieties.

Cultural Repertoire of Signscontextual condition

The finite, heterogeneous, and 'pre-constrained' set of available elements (images, words, myths, debris of events, manufactured objects) which already possess a sense from their previous uses and serve as the raw material for new intellectual constructions.

Science of the Concretepsychological state

A mode of scientific thought parallel to modern abstract science, which operates at the level of sensible perception and imagination. It structures the world using signs—which are halfway between percepts and concepts—and organizes knowledge through analogies and correspondences based on observable qualities.

Intellectual Bricolagepsychological state

The characteristic mental process of the 'science of the concrete', which constructs structured sets (myths, classifications) not from first principles but by rearranging and fitting together elements from a limited, pre-existing cultural repertoire ('whatever is at hand').

Logic of Concrete Oppositionspsychological state

The fundamental logical operation of mythical thought, which creates meaning by establishing systems of homologies between two or more sets of differences, such as the perceived differences between natural species and the instituted differences between social groups.

Creation of Classificatory Systemsoutcome metric

The outcome of the science of the concrete, resulting in well-articulated, multi-level taxonomies (e.g., totemism) that systematically order the natural and social universe by assigning everything a place within a structured whole.

Intelligibility of the Universeoutcome metric

The perception of the world as a meaningful and ordered cosmos, where every element has its place and is connected to other elements through a web of systematic correspondences, leaving nothing meaningless.

Social Cohesion and Articulationoutcome metric

The functional state of a society where social groups are clearly differentiated from one another based on a conceptual model (often natural), yet are integrated into a cohesive whole through structured systems of reciprocity and exchange (e.g., of women, goods, or services).

Conceptual Inter-Translatabilityoutcome metric

The property of a cultural system whereby its classificatory framework acts as a master code, allowing for the conversion of ideas, messages, and structures between different levels of reality (e.g., nature and culture, myth and social structure, economics and religion).

The story

The reader The reader is an intellectually curious individual—perhaps an academic, student, or layperson—who wants to understand different ways of thinking and how human societies create meaning. They are dissatisfied with simplistic, evolutionist views of 'primitive' cultures.

External problem

The reader lacks a coherent framework for understanding the seemingly bizarre and illogical beliefs and practices of 'primitive' societies, such as totemism. They are confronted with a disorganized mass of ethnographic data that defies easy explanation.

Internal problem

The reader feels frustrated and perhaps ethnocentric, unable to grasp the intellectual sophistication of 'savage' thought. They suspect there is a deeper logic but cannot access it, feeling intellectually disconnected from other forms of humanity.

Philosophical problem

It is wrong to dismiss vast swathes of human intellectual history as pre-logical or infantile. This hierarchical view of human cognition perpetuates a colonialist mindset and prevents us from understanding the full range of human intellectual capabilities.

The plan

Recognize the 'Science of the Concrete': Understand that 'savage' thought is a legitimate, systematic, and intellectually driven way of knowing the world.
Adopt the 'Bricoleur' Model: Learn to see mythical thought as a form of 'bricolage' that creatively rearranges existing cultural elements (signs) to build new structures of meaning.
Master the Logic of Classification: Analyze how 'primitive' cultures use systems of binary oppositions and homologies (especially between nature and culture) to create elaborate and meaningful classifications like totemism.
See Systems of Transformation: Appreciate how different cultural domains (myth, ritual, kinship, art) are all interconnected and can be understood as transformations of a common underlying logical structure.

Success

The reader achieves a profound understanding of the unity of the human mind.
They can see the world through different cultural lenses and appreciate the logic and beauty in systems of thought that once seemed alien.
They become a more sophisticated analyst of culture, able to decode the myths and symbols not just of 'primitive' societies, but also their own.

At stake

The reader remains trapped in an ethnocentric worldview, seeing other cultures as irrational and inferior.
They continue to view human history as a simple, linear progression from superstition to science, missing the rich diversity and parallel validity of different modes of human thought.

Questions this book answers

Is 'savage' or 'primitive' thought fundamentally different from and inferior to modern scientific thought?
How do non-literate societies classify and make sense of their world?
What is the underlying logic of totemism and other seemingly exotic classificatory systems?
What are the fundamental mental operations common to both mythical thought and scientific thought?
How can we understand the relationship between nature and culture in human thought?
