“…The need for objective behavioural indicators is particularly acute in the context of COVID-19, where the combination of high anxiety levels and need for effective treatment may foster misinformation-driven demand for remedies that are ineffective and often dangerous, including bleach, methylated spirits, or essential oils (e.g., Spinney, 2020; note, however, that for ethical reasons we selected a product for the current study that is unproven as a COVID-19 treatment but relatively safe). Given the well-established attitudebehaviour gap (e.g., McEachan, Conner, Taylor, & Lawton, 2011), it is critical that studies take steps towards investigating how misinformation affects behaviour, and to what extent corrections can undo those effects (Hamby, Ecker, & Brinberg, 2020).…”
