Customer reception: does an accent change perceived credibility?
In Basel, reception at a pharmaceutical site, a life sciences laboratory or a Rhine logistics provider regularly brings together people with different language backgrounds. The management question is specific: when equivalent information is provided, does an accent prompt requests for additional evidence that other visitors are not asked to supply?
What the literature establishes
Shiri Lev-Ari and Boaz Keysar (2010, Journal of Experimental Social Psychology) studied the credibility of trivia statements spoken in English with different accents. In their experiments, statements delivered with a non-native accent were rated as less true than those delivered with a native accent. This finding concerns an experimental judgment about statements, not a measure of speakers' honesty or competence.
Ease of processing as a misleading cue
Rolf Reber and Norbert Schwarz (1999, Consciousness and Cognition) showed that ease of reading, manipulated through visual contrast, could alter truth judgments. Their study does not concern accents, but it illuminates a relevant mechanism: information that is easier to process can seem more true. In reception work, the hypothesis worth examining is therefore whether the effort of understanding is sometimes wrongly attributed to a lack of reliability on the speaker's part.
The premature conclusion
One might conclude that employees should be trained to ignore accents. That would confuse a genuine difficulty in understanding with an unwarranted judgment about the person. The aim is not to stop asking people to repeat information, but to distinguish clarification from an additional demand for evidence. (our executive and employee training programmes)
What the data do not establish
These experiments do not demonstrate that visitors with an accent systematically receive less favourable treatment in Basel businesses. They reproduce neither extended multilingual exchanges nor the security, confidentiality and access requirements of industrial sites. A difference in verification may be legitimate when it addresses missing information or a rule that applies to everyone; accent alone cannot explain it.
A practical check in Basel
Within SHR's « Accueil client » programme, a simulation can use requests recorded with consent by several speakers with different accents, providing identical information for an international R&D visit, a pharmaceutical appointment or a delivery linked to Rhine logistics. Before the exercise, the manager specifies the evidence required for each scenario; the measure is then, for each recording, the proportion of responses requesting additional evidence beyond those requirements, distinguishing these requests from simple clarification. Random presentation order and multiple voices reduce some confounding factors without perfectly isolating the effect of accent: a difference is a signal to investigate, not proof of discrimination.
