In the Hidden Brain podcast, host Shankar Vedantam explores how language analysis can provide insights into a person's psychology and mental states. James Pennebaker explains his research on how subtle differences in the use of pronouns, articles, and other function words reveal information about depression, anxiety, deception, and even relationship success.
The blurb touches on various applications of language analysis, from criminal cases to romantic partnerships. It highlights how an individual's word choices can be an "x-ray" into their innermost thoughts and feelings, shedding light on topics like hormones' influence on language and the predictive power of analytic writing. Join the discussion on the fascinating psychological insights hidden in our everyday speech patterns.

According to James Pennebaker's research, analyzing a person's use of function words like pronouns, prepositions, and articles can provide an "x-ray" into their innermost thoughts and feelings. Small differences in the usage rates of these words can indicate significant changes in psychological states like depression, anxiety, or deception. However, Pennebaker stresses that language analysis is a diagnostic tool, not a means to directly change mental states.
Pennebaker found that women tend to use more pronouns, reflecting a greater social orientation, while men use more nouns and articles, indicating a focus on objects and abstract concepts. He also observed that after taking [restricted term] supplements, individuals showed a decrease in third-person pronoun usage, suggesting a reduced interest in others.
In criminal cases, language analysis can reveal signs of deception, depression, or premeditation. For example, Pennebaker's analysis of Kathleen Fulbright's diaries cast doubt on her conviction by showing a lack of hostility or anger.
Pennebaker's research also revealed that "language style matching" between romantic partners can predict relationship success better than the partners' own assessments. Post-breakup, people show increased anxiety and self-focus in their language. Additionally, analytic language in college essays predicted academic performance.
1-Page Summary
Language patterns can reveal important details about a person's mental health, emotions, and personality traits. James Pennebaker's work in analyzing language has opened doors to understanding the psychological underpinnings behind the words we use.
By breaking down language through computer programs, Pennebaker uncovered that function words such as pronouns, negations, prepositions, and auxiliary verbs can serve as an "x-ray" into our innermost thoughts and connections with others. These words, often overlooked, can tell us much about how individuals see the world and relate to their environment because they are used automatically and unconsciously, indicating underlying psychological states.
Pennebaker's research illustrates that the function words we use, which might seem insignificant in daily communication, are remarkably revealing of our social orientation, attention focus, as well as our thinking processes. He maintains that function words can tell us a lot precisely because they are invisible and uncontrollable, and we often do not realize how much of ourselves we are exposing when we use them. These words provide insights into a myriad of psychological aspects, from our social connectedness to our power dynamics in relationships.
The use of pronouns, particularly "I words", can be indicative of someone's social connections, with a higher frequency pointing to greater social involvement. However, this pattern could also reflect self-focus, which has been associated with anxiety, depression, and physical pain. For instance, Pennebaker found that people who are depressed tend to use "I words" at higher rates, sometimes showing a usage change from 4-5% to 6%, which is a substantial statistical difference.
When analyzing leadership roles, there is a noticeable shift from the use of "I" words to "we" words, suggesting a move from self-focus to grou ...
The insights language can provide about psychological states and personality
Research has provided insight into how gender and hormones can influence the nuances of language, revealing interesting patterns in how men and women communicate.
According to James Pennebaker's research, women are more likely to use first-person singular pronouns such as "I," "me," and "my," whereas men use plural pronouns such as "we," "us," "our" at a rate similar to that of women. Men, on the other hand, tend to use more nouns and articles, reflecting a stronger focus on objects and tangible things.
The disparity in the use of language between men and women suggests deeper differences in perception and engagement with the world around them. Women's frequent use of pronouns indicates a general interest in interpersonal relationships and social dynamics. In contrast, men's language, with a higher use of nouns and articles, tends to point toward an orientation around objects and more abstract concepts.

How language patterns differ based on gender and hormones
The use of language analysis has expanded into various fields, including criminal investigations and relationship prediction. James Pennebaker's work sheds light on how subtle language cues can reveal important insights into a person's psychological state and how they interact with others.
Years after Kathleen Fulbig was found guilty of murdering her children, her lawyer contacted James Pennebaker to analyze her diaries. Pennebaker's expertise in language analysis focuses on function words to detect changes in psychological states such as deception and depression. In his assessment, Pennebaker looked for signs of instability, hostility, premeditation, or any significant psychological changes that would corroborate the conviction.
Pennebaker observed that Fulbright's language did not change notably as it got closer to her child's death—a change that would be expected if she were planning to commit murder. The high rate of word repetition and diminished emotion in her writings suggested that Kathleen was likely suffering from postpartum depression, not actively plotting a crime. Her use of cognitive process words like "think," "believe," and "wonder" was higher than usual, contradicting the notion of premeditated guilt. Pennebaker concluded that Fulbright's diaries lacked any indicators of deceitful anger or hostility, which led the appeals court to question her guilt, resulting in her exoneration.
Pennebaker's research delved into the predictive power of "language style matching" during speed dating sessions. He found that this factor—how well two individuals' speech patterns align—could forecast whether pairs would go on future dates more accurately than their personal impressions of the date. In a separate study of college freshmen couples, those with above-average language style matching scores had a nearly 80% chance of remaining together after three months, ...
