Did You Doublecheck Your Online Dating Profile Bio?

Here's why you should watch out for language errors.

Key points

  • Language errors in dating profiles may indicate a lack of intelligence, and intelligence is generally judged as being attractive.
  • Peole whose dating bios contain language errors are rated as less socially and romantically attractive.
  • Language errors and picture clarity influence judgements of attractiveness in different ways.

In online dating, it is a profile owner’s photos displaying their physical appearance and manner that viewers generally use to form an impression of that person. However, some dating sites blur out the profile photo until a match has occurred, and therefore, in the absence of such visual information, it is perhaps the dating profile bio to which viewers refer in order to form an impression of the profile owner. So it's important that profile bios are constructed carefully and do not contain errors in typing, grammar, or spelling. Such errors may influence impressions of intelligence, which is important because intelligent people are often judged as more attractive compared to their less intelligent counterparts.

Tess Van der Zanden and colleagues from Tilburg University in the Netherlands sought to assess the effects of language errors in dating profile bios. Participants in their study were divided into two groups, with one shown a blurred photo and the other shown a non-blurred photo. Following this, each group was further subdivided and was shown either a written dating profile bio which contained language errors or one which had no errors.

To check on the extent to which the participants had actually read the profiles, they were asked to answer two questions about the profile content before being asked to rate it. The profile photos used in the study were prejudged to be of average physical attractiveness and were paired with four written profiles which differed in some relatively neutral content. The texts presented were identical for men and women participants except for one gender-specific word (his/her) (Van der Zanden, Schouten, Mos, & Krahmer, 2020).

Bios containing language errors, which were evenly dispersed throughout the text, included the following examples:

  • “I just feel like I want to fall love again” (typographical error)
  • “That you laugh Together about the things you experienced” (capital letter error).

Attractiveness ratings for each profile were assessed in four ways, which were:

  • Physical attraction: “I think this person is good-looking.”
  • Social attraction: “I think I could be friends with this person.”
  • Romantic attraction: “I would want to have a relationship with this person.”
  • Dating intention: “I would like to know more about this person.”

Language Errors and Attractiveness

Firstly, it is worth reporting that only 33.5 percent of participants reported noticing any language errors in the profiles with which they had been presented. The rest reported not noticing any language errors or were unsure. However, participants who had noted language errors rated the owners of these bios as less socially and romantically attractive than people whose profiles featured no language errors. In other words, they didn’t feel they could have a romantic relationship or even be friends with them. However, there were no differences between the owners of bios featuring errors and bios featuring no errors on participants’ ratings of physical attractiveness or dating intention: that is, they didn’t rate them as less physically attractive or weren’t less curious about them.

Furthermore, profiles which featured visible unblurred pictures were judged as more physically attractive than pictures which were blurred. However, there were no differences in ratings between blurred and non-blurred pictures for ratings of social attractiveness, romantic attractiveness, and dating intention. So, the blurred images did not make participants feel that they couldn’t be friends with or have a relationship with and weren’t less curious about the profile owners.

Overall, however, the findings show that language errors and picture clarity appear to influence judgments of different elements of attractiveness.

The researchers also expected that any adverse effects of poor language might be magnified for the blurred profile pictures compared to the non-blurred images. However, this was not the case, meaning that the absence of visual cues did not cause an increase in the importance attached to the textual information. Furthermore, when the researchers compared the effects of language errors compared to no language errors in the blurred and then in the non-blurred photo conditions, they found no effect on the various measures of attractiveness.

While the take-home message for online daters is to take care not to make language errors in their dating bios, it also should be recognized that this study used a broad range of language errors, and it is entirely possible that certain specific types of errors may influence different elements of attraction. The researchers did examine this in a second study, which will be featured in another post.
