One of life’s fundamental truths is that people with chocolate are the most popular. And now there’s scientific evidence to prove it.

Giving a student a chocolate cookie has a been found to have a huge impact on how students feel about their teachers, according to new research.

The study, to be published in the journal Medical Education, found that tutors who gave their university students chocolate cookies scored significantly better in evaluation surveys than those who were given nothing.

These cookie-giving tutors were also rated as having better teaching materials, and their overall scores for the quality of their course were better.

The researchers said that their findings might just give teachers new ideas if they want to improve their evaluation scores using “food-related interventions”. I.e. giving them chocolate.

So the motto of all this? Let’s all just give each other chocolate, and the world will be a happier place.
