How is Watson playing 2 Truths and a Lie?

While it’s impossible to say with 100 percent certainty whether a person is lying or not, there are both visual and verbal clues that provide indicators. This game is built with IBM Watson, and uses a unique set of cognitive technologies to analyze these clues to play “2 Truths and a Lie” just like people do.

Watson plays “2 Truths and a Lie” by analyzing each video statement using three key cognitive technologies: Watson Visual Recognition, Watson Speech to Text, and Watson Tone Analyzer.

Using Cognitive Technology to separate fact from fiction

Watson is able to cull through millions of data points to help distinguish between fact and fiction. Watson was trained on thousands of unique images of human faces associated with basic emotions (anger, disgust, fear, happiness, sadness, surprise, neutral) to identify the emotions being displayed in each recorded video statement. This data is the representation of the ‘ground truth’ used by the Watson Visual Recognition API.

The Watson Speech to Text API creates a transcript of the statement from each recorded video. Watson Tone Analyzer API then analyzes this transcript to detect three types of tones from text: emotion, social tendencies, and language style. The API identifies emotions like anger, fear, joy, sadness, and disgust; social tendencies from the Big Five personality traits used by psychologists (openness, conscientiousness, extroversion, agreeableness, and emotional range); and language styles that include confident, analytical, and tentative.

IBM Watson plus Havas Cognitive

Custom logic, developed by Havas Cognitive in partnership with IBM Watson, uses all of the above data to evaluate a weighted mathematical model of a ‘lie vs. truth’ score; where negative scores are considered 'lies', and positive scores are considered 'truth'. Watson then identifies the lie as the statement with the lowest ‘lie vs. truth’ score.

Please keep in mind that a high or low confidence percentage is a relative indicator. While playing, people may see low confidence percentages that are still identified as a lie. This is similar to the real game, when people playing are challenged to separate fact from fiction, and have to make a decision in the moment using the best available information.

Watson is IBM’s platform for cognitive business

IBM Watson is a technology platform that uses natural language processing and machine learning to reveal insights from large amounts of structured and unstructured data.

Cognitive technologies can help you:

  • Answer your customers’ most pressing questions
  • Quickly extract key information from all documents
  • Reveal insights, patterns, and relationships across data

2 Truths and a Lie: The game

The game “2 Truths and a Lie” is a popular icebreaker that people play to learn about one another. Here’s how you would play with friends:

  • One person lists three "facts" about themselves, except one of the "facts" is a lie.
  • Other people guess which statement is a lie. In this case, Watson will guess using cognitive capabilities.
  • The person sets the record straight by revealing the lie, e.g., #2 was a lie.
