This is a lengthy PowerPoint with built-in activities that will require access to the Internet. It takes approx. 2-3 days to complete the activity, with one day for lecture and one or two days to complete the MBTI.
The lecture walks students through what the four Elizabethan humors are, what they mean, and how each supporting character in Romeo and Juliet represents one of the four humors. You can explain to students that this was a kind of personality test, and an easy way for Shakespeare to use indirect characterization.
The lecture then moves forward with comparing humorism to something like the Myers-Briggs Type Indicator as a measure of one's character. Students then use a website (URL included) to take the MBTI in character, as either Romeo, Mercutio, Benvolio, or Tybalt. Then they take the test for themselves and use their MBTI to determine what humor is out of balance for them.
This was a very fun lesson and students enjoyed taking the personality tests, both as characters and as themselves. The end goal is to have a productive class discussion about the characters in the play and how students can relate to them.
