Publish the Obsidian vault's Knowledge folder as /knowledge (881 notes, 67 folders), with a Knowledge item in the nav and footer. - scripts/import_knowledge.py regenerates data/knowledge from the vault: slugged paths, folder notes as index pages, wikilinks resolved to site links (or plain text), callouts, highlights, and Dataview tables rendered statically. Personal notes are withheld via an exclusion list plus a privacy guard. - tuftecms/core/knowledge.py builds a concept index from note titles and aliases. First mentions on ordinary pages link to their Knowledge note (capped, never in headings, code, links, or sidenotes); Knowledge pages list related notes and where they're mentioned across the site; other pages get a Related Knowledge block. - Knowledge URLs join sitemap.xml (so the sweep test covers them), never displace existing legacy slugs, list alphabetically, and mermaid diagrams render client-side only on pages that have them.

Mary Ainsworth
Bowlby built the theory. Ainsworth sat in living rooms for years and found out whether it was true.
Overview
Mary Ainsworth (1913–1999) was the empirical genius of attachment theory — the researcher who turned John Bowlby's grand evolutionary claims into something you could observe, code, and test. Trained at Toronto under William Blatz, whose "security theory" already held that a child uses the parent as a base of operations for exploring the world, she joined Bowlby's research team at the Tavistock Clinic in 1950 and spent the rest of her career answering the question theory alone could not: what does attachment actually look like, one mother and one infant at a time?
Uganda and Baltimore
The fieldwork came first. In 1954, Ainsworth moved to Uganda and spent months in the villages near Kampala observing twenty-six Ganda families — unhurried, naturalistic observation of babies and mothers going about their lives, published as Infancy in Uganda (1967). There she saw the pattern that became the theory's anchor: the infant using the mother as a secure base, venturing out, checking back, retreating to her when frightened. She also saw the variation — some babies confident in that rhythm, others clingy and fretful, others oddly indifferent — and noticed that the variation seemed to track the mother's availability and responsiveness.
Baltimore made it systematic. In her longitudinal study there, Ainsworth's team visited twenty-six homes every few weeks for the entire first year — some seventy-two hours of observation per family — coding feeding, crying, holding, and play. Out of this came her maternal sensitivity scales: the finding that what predicts a secure infant is not how much a mother holds or feeds, but how accurately and promptly she reads the baby's signals and responds to what the baby actually needs. Sensitivity, not quantity. Attunement, not indulgence — the empirical answer to a generation of experts who warned that picking up a crying baby would spoil it. Ainsworth's data said the opposite: answered cries produce children who cry less.
The Classification System
To see in the lab what she had seen in homes, Ainsworth designed the Strange Situation — the twenty-minute separation-and-reunion procedure that became developmental psychology's most famous instrument. From it came the three original classifications: secure (B), avoidant (A), and anxious-ambivalent (C), each pattern mapping back onto the caregiving history her home visits had documented. Patterns of Attachment (1978), written with Blehar, Waters, and Wall, is the landmark text. Her student Mary Main would later find the fourth pattern hiding in the unclassifiable tapes — Disorganized Attachment — and carry the framework into adulthood with the Adult Attachment Interview. The lineage is direct: Bowlby's theory, Ainsworth's method, and everything since built on the two of them.
