The Blue Pen Theory

After examining some of my old test papers, I noticed something intriguing. I had studied about the same for each one, but there was something quite subtle, though now seemingly obvious, that I had not realized before. This particular trend was not just limited to one subject. In fact, it was apparent in every subject. I call this trend ‘The Blue Pen Theory.’

For years industrial psychologists have known the effect colors have on the human psyche. Increased work output and more prolific spending can result all because of a little strategic use of color.

From Sensational Color:

• In Chinese culture, colors corresponded with the five primary elements, the directions, and the four seasons. Blue was associated with wood, east, and spring.
• Blue, blue-green, and green are sacred colors in Iran, where they symbolize paradise.
• In India, paintings of the god Krishna often depict him as having blue skin.
• In the United States, post office mailboxes are typically blue.
• In Mexico, blue is the color of mourning.

• In Aztec culture, blue symbolized sacrifice.
• In Greece, the color blue is believed to ward off “the evil eye.” Those who believe in this Greek superstition often wear a blue charm necklace or blue bracelet for protection.

In every instance I used a blue pen, my grade was nearly ten percentage points higher. My accidental discovery of the correlation between my grades and the usage of blue ink got me thinking. What other ‘blue pens’ can students add to their test-taking arsenals? This all may have been a coincidence, but who knows. It doesn’t hurt to try. The next time you have a test, unless black is required, try using a little happy blue. You may be surprised with the results.

(If you are in Mexico you might want to avoid this…unless you are writing an obituary.)
