Bales then became a professor at Harvard, working in the university's Laboratory of Human Relations. In 1950, Bales published a book titled Interaction Process Analysis: A Method for the Study of Small Groups in which he described in great detail his musings of human interaction within small groups.

Interaction Process Analysis
The goal of this method was to capture direct face-to-face interaction as they takes place, then to analyze the interactions into useful information. In order to capture an interaction, Bales’ method utilized observers. The observer's job is to interpret and categorize the observed behavior. This is not without error as the observer must infer intent and meaning of the observable action. The observer is supposed to be well trained on the variables they are categorizing and they should be able to do it effortlessly; however, human raters bring with them their own preconceived schemas and heuristics. Human raters are subject to subconscious biases and fallacies. To circumvent this pitfall, Bales’ method makes use of multiple observers and an inter-rater reliability is then derived from both raters’ produced data. Bales’ method was formed under two assumptions. The first assumption is that the observer must assume that all small groups are similar in that any given group contains a variety of people, or follows a normal distribution of variance. These group members share task problems that materialize in relation to their situational context, but also socio-emotional problems that materialize in the interaction with other members of their group. The second assumption is that each individual's behavior can affect those problems. Observers must categorize each individual's behavior continuously, capturing behavior as a sequence of events through time. The unit of measure is the smallest discriminable segment of verbal or nonverbal behavior the observer can differentiate and classify. He referred to the content of these categories to be “process content” as opposed to the topical content. Bales claimed process content, which later became known as group process, was at the core of small groups; what remained when situational variance was stripped away.
SYMLOG
The use of SYMLOG and the certification of SYMLOG consultants is now maintained by the SYMLOG Consulting Group, whose formation Bales supported. In 2016, the group honoured the centenary of Bales' birth by publishing excerpts from a video interview which he gave in 1996.
