Can the font used for important medical instructions affect how well patients follow them?
The answer probably won’t surprise regular Neuromarketing readers. A study found that the font used to present medical instructions did indeed affect how those instructions were perceived. The scientists found,
• Font influenced pregnant women’s perceptions of an antenatal intervention.
• The easier the font was to read, the less complex the intervention was perceived.
• The font of written information may also determine adherence to interventions.
According to the lead researcher, Dr. Andrew Manley, “When it comes to people engaging with written information related to their health and wellbeing, it is vital that it is presented in the most accessible format.”
What’s Going On?
Why would something as apparently irrelevant as a type font change people’s beliefs about important medical instructions? The culprit is cognitive fluency.
When our brains have difficulty processing something, that unconscious extra work can be “transferred” to something else and make that task seem more complicated or time-consuming.
In the new study, when the patient instructions were presented in a “disfluent” (harder to read) font, the described activities themselves seemed more complex and difficult. The text, of course, was identical – it was purely the font that made the program seem more difficult.
Bad Fonts Can Kill Your Marketing, Too
If patients getting important medical information are affected by the fonts used to present the information, it should be no surprise that similar effects are evident in many other domains.
In Convince with Simple Fonts, I describe research that shows people estimated it would take twice as long to perform a simple set of exercises when the two-sentence description was printed in Arial (simple) rather than Brushy (a somewhat fancier font).
Choosing the wrong fonts can add invisible friction to your marketing.
The font that your graphic designer picked may look great and differentiate your marketing from that of other brands, but it may also make it seem more difficult to place an order or request information.
When you are trying to get a web visitor (or reader, etc.) to take some action, “difficult” is the opposite of what you are striving for. If you ask a visitor to complete a short form, for example, showing the instructions in a fancier font will make that task seem (unconsciously, of course) more difficult. Your conversion rate will be lower.
Which fonts to avoid? I’ve never seen a comprehensive list of fonts ranked by fluency, but in general I’d avoid conspicuously decorative fonts: script, embossed, heavy italic, unusual letter shapes, etc. You can trust your instinct – if it seems a bit more difficult to read when you first glance at it, the font is probably not as fluent as it should be.
Whether you are delivering critical medical information or simply trying to turn a web visitor into a lead or buyer, the K.I.S.S. maxim applies to your fonts and presentation: Keep it Simple, Stupid.
So, if your designer presents you with text in a totally cool, unique font, don’t hesitate to reject it – science is on your side!
