11. Linguistic Inquiry and Word
Count
 More commonly known as LIWC
 Designed by James W. Pennebaker,
Roger J. Booth, and Martha E. Francis
 Developed in 2007

12. What is LIWC?
 Text analysis software
 Calculates the degree to which people
use different categories of words
 Determines use of:
 positive emotions
 self-references
 negative emotions
 Social words
 70 other language dimensions.

13. Sample Text
Sometimes I feel as though there are two
me's, one coasting directly on top of the
other: the superficial me, who nods when
she's supposed to nod and says what she's
supposed to say, and some other, deeper
part, the part that worries and dreams...
Most of the time they move along in sync
and I hardly notice the split, but sometimes
it feels as though I'm two whole different
people and I could rip apart at any second.

15. Linking LIWC to Personality
 The Seventh International Conference on
Internet and Web Applications and
Services
 Three doctorate scholars from University
of Patras, Greece
 Presented a research paper based on
using LIWC to pinpoint personality types.

16. Linking LIWC to Personality
contd…
Using the scores of the language dimensions
given by LIWC recruiters can easily pin down
the personality type of candidates using
multiple regression analyses e.g.
E = S + 1.335*P – 2.250*N
E = 8.86 + 1.335(1.27) – 2.250(1.27)
E = 7.69795

17. Ethical Considerations
 A core ethic of the MBTI assessment is that
results are given only to the respondent.
 Candidates should be informed
beforehand if they are to be
psychologically analyzed.
 Any personality type resource you use
should clearly respect the value of
diversity.
