A weakness of attachment on childhood and adult relationships?

-Criticism is that reaserch into early attachment is that it is overly deterministic in the assumptions it makes -Research into the impact of attachment type of childhood and adult relationships have very set views on the outcome for future behaviour -Eg: an infant with an insecure attachment type will be doomed to experience poor quality and unsatisfying relationships in later life as a result of the internal working model -Taking this approach suggests that there is no room for an alternative path to unfold. Reserach has, in fact, documented instances of happy relationships in adulthood despite a troublesome start meaning Bowlby has overestimated the role of the internal working model
