What is a weak thesis?

Many students don’t know the difference between a weak thesis and a strong thesis.  Here are some clues that show that an essay’s thesis is weak:

A thesis is weak if it is already known to be true, so there is nothing new to be explored.  For example,

  • Smoking is bad for human health.
  • Benjamin Franklin was an 18th century inventor.
  • The New England Patriots are a great football team.

A thesis is weak if it is a personal belief, not something to be investigated.  For example,

  • Summer is the best season.
  • Middle school is harder than elementary school.
  • Abraham Lincoln ranks number one among US Presidents.

The thesis is weak if it is too broad to be thoroughly investigated.

  • Hurricanes are dangerous storms.
  • Nancy drew books appeal to girls.
  • Romeo and Juliet is a tragedy.

The thesis is weak if it does not make a claim needing to be proven.  For example,

  • Dr. Seuss wrote popular children’s books.
  • Being a police officer is both good and bad.
  • In chess, each piece moves in particular ways.

The thesis is weak if it is not controversial, not a statement over which people can disagree.

  • Barak Obama was the 44th President of the US.
  • No human being has lived for 130 years.
  • Alex Fleming’s discovery of penicillin mold was one the greatest medical discoveries of the 20th century.
