Dr. Warren's Primary Areas of Expertise

Lying & Self-deception

From seemingly small white lies to full-blown criminal confabulations, humans are master liars. Not only do we deceive others, but we lie to ourselves on a daily basis.

Eating Disorder & Body Image

We are in the midst of a health crisis. In the United States, the majority of our population is obese or overweight; most us of are dissatisfied with our physical appearance; and, we have the highest rates of diagnosed eating disorders in history.

Exaholics | Relationships

Romantic relationships offer us one of the greatest opportunities to understand ourselves. Like a great therapist, a romantic partner can reflect back a part of you.

Multicultural Competency

Race. Class. Gender. Sexual orientation. Sexual identity. Culture. Age. Weight. Oppression. White privilege. These are not ​topics that most want to ​discuss.

Getting tenure and then quitting is not the typical trajectory of a university professor. Yet, Dr. Warren did just that.

During her TEDxUNLV talk, “Honest Liars: The Psychology of Self-Deception, ”Dr. Warren describes how we lie to ourselves, the profound costs of our self-deception, and how to be more honest with ourselves. For when we are honest with ourselves, we have the opportunity to change.

Lies We Tell Ourselves: The Psychology of Self-Deception

Dr. Cortney S. Warren's book speaks to these questions about the human condition:

  • How can I be happier?
  • How can I have more successful relationships?
  • What is my purpose in life?
  • How can I help myself change?

At their core, most of these questions boil down to one central question:

How can I live a more fulfilling life?

Lies we Tell Ourselves

"Humans are masters of self-deception.

We don’t like to think of ourselves as liars; it hurts us too much to admit. So we lie to ourselves about that, too.

Unless we actively Choose Honesty."
