No.5 of 36 Automation Bias

Automation bias is the propensity for shoppers to favour suggestions from automated decision-making systems and to ignore contradictory information made without automation, even if it is correct.

Automation bias refers to a specific errors shoppers make in highly automated decision making contexts, when many decisions are handled by automated aids (e.g. when the checkout operative scans your numerous items and the till just tells you the total cost, discounts and offers factored in too).

Automation bias occurs when the brain of the shopper is only there to monitor on-going tasks. Errors occur when the shopping brain does not notice an automated decision aid failure (e.g. when the checkout fails to pick up on a special offer).

There are three main factors that lead to automation bias. First, the human tendency to choose the easiest mental approach to decision-making. Second, the tendency of humans to view automated aids as having an analytical ability superior to their own. Third, the tendency of humans to reduce their own effort when sharing tasks, either with another person or with an automated aid.

With bricks and mortar store and online becoming ever more automated, you need to provide shoppers with trustworthy automation to ensure they are free to safely employ this bias. If your store/brand/website is to hard to think about, they might well go elsewhere. Here are ways to address automation bias.

  1. Communicate trust at all stages – The more shoppers trust your automation, the more they will be happy to apply automation bias, ergo the more they will like your brand.
  2. Address any errors quickly and effectively - We’ve all seen it, a special offer that says 1 product for £1 of buy 2 for £2.50. Such spreadsheet related errors are a sure-fire way to lose the trust of shoppers.So go beyond just correcting the error, make a song and dance how it will never happen again (think Tesco horse meat scandal of a few years ago).
  3. Make it easier – Analyse the purchase process and see whether in the current day and age, you can introduce automation that will make it easier to buy. Self-checkouts are note easier, they simply save the retailer money in terms of staff costs. Conversely, Washed, prepared and bagged vegetables are easier to prepare and consume, shoppers trust the customisation and pay a premium for it.

In summary, automation bias can be a good thing for both brands and retailers; as long as it works and is trusted by shoppers. Lose the trust, lose the shoppers!
