Short Description:
To evaluate the readability of such materials in a more robust and transparent manner, the Humane Research Council (HRC) partnered with VegFund and FARM to test a selection of outreach materials that are commonly used by vegan advocates. The average readability scores placed these materials in the range of the 11th grade reading level or higher, which is three to four grade levels higher than the average U.S. adult.

Abstract:
Summary of Results (from report):
  • The average U.S. adult has a 9th or 10th grade reading level, and 44% of adults have an 8th grade reading level or lower.
  • HRC recommends developing vegan outreach materials at a 7th or 8th grade reading level in order to ensure comprehensibility for a large proportion of the target audience.
  • However, all of the vegan outreach materials evaluated in the current study are written at an 11th grade reading level or higher, indicating that the vegetarian movement’s most popular materials might be incomprehensible to half or more of the target audience.
  • Based on six readability tests, the average readability scores ranged from a low reading level of 11th grade for PCRM’s vegetarian starter kit to a high of 15th grade (beyond college level) for the Humane Myth brochure.
  • Additional research including focus groups (and possibly one-on-one interviews) would allow a more comprehensive evaluation of the materials beyond basic readability. HRC recommends a collaboration to conduct additional qualitative research at a cost of $8,000 to $12,000.

Readability

I think this study is very important. The example of the fish suffering, in its original form and then in its revised form, shows how powerful language can be. I wasn't clear on how pictures affect readability, though, and would have liked to understand that concept. If I am ever in a position to develop literature, I will keep this study in mind. Short sentences with the fewest syllables possible.

Great Study

This is a terrific study. When I used to consult for the pharmaceutical industry, one of my tasks was producing consumer literature at a 6th grade reading level. We used a sophisticated, trademarked system to count syllables, sentences, etc. to ensure that we were meeting our goal (illustrations were taken into consideration as well). Any consumer piece that did not meet a 6th grade reading level was not approved. This is part of the reason why big businesses have been so convincing--they are reaching their audience with a message that the audience can understand--even if it is the wrong message. As Davids to these companies' Goliaths, it is imperative that we utilize the same strategy in producing consumer material if we really want to persuade people and effect change. Fortunately, COK will be updating its Vegetarian Starter Guide within the next year, and the findings of this study will be strongly considered in our revision. Thanks for the good work.
