I got the book by the author (<i>Attachment Theory in Practice: Emotionally Focused Therapy (EFT) with Individuals, Couples, and Families</i> by Susan M. Johnson) on kindle but haven't read it yet. I was on a book buying binge a few weeks ago for anything related to attachment theory.<p>More on EFT: <a href="https://en.wikipedia.org/wiki/Emotionally_focused_therapy" rel="nofollow">https://en.wikipedia.org/wiki/Emotionally_focused_therapy</a><p>Regarding attachment theory itself: A major paper in adult attachment theory is <i>Romantic Love Conceptualized as an Attachment Process</i>, <a href="https://pdfs.semanticscholar.org/1d36/ac75d7081fcd86d467f6d2ef408d60c8ffca.pdf" rel="nofollow">https://pdfs.semanticscholar.org/1d36/ac75d7081fcd86d467f6d2...</a>.<p>For further reading, stuff by Cindy Hazan, Phillip Shaver, Mario Mikulincer is good<p>Attachment theory originally was focused on early stage development in children by John Bowlby. Later it was expanded as a way to conceptualize relationships beyond the child and caregiver, things like friendships, work colleagues, bandmates, etc.<p>Examples where modern attachment theory could be used formulate a hypothesis (or analyze if you have more than conjecture):<p>- why a band breaks up<p>- why CrunchPad failed (<a href="https://techcrunch.com/2009/11/30/crunchpad-end/" rel="nofollow">https://techcrunch.com/2009/11/30/crunchpad-end/</a>)<p>- in interpersonal relations, contradictory, anxious, afraid, erratic behavior - or on the other hand - secure and trusting around someone or a group.<p>Attachment can explain lasting, functional relationships.<p>I guess in HN-speak, there could be dyads between startup co-founders, founder <-> employee, investor <-> founder, employee <-> employee. Those cooperational things bubble up into group dynamics and product formation / stuff shipping.<p>New startup idea: Founder therapy :)
