Does scarcity — low stock, ticking clocks — change who wants an AI shopping assistant, or just how much everyone wants one?

This explores whether scarcity (limited stock, time pressure, hard-to-get items) changes who wants a high-autonomy AI shopping assistant, or whether it changes why people want one. The most direct evidence in the collection supports the second reading. Across five studies, including real ad click-through data, the deciding factor was not a type of person. Specifically, it was not consumers who feel powerful and in control. What mattered was how much benefit people expected the assistant to deliver. Scarcity raised that expected benefit, and adoption rose with it What drives shoppers to accept autonomous AI assistants?. So scarcity doesn't seem to sort shoppers into adopters and holdouts. It makes the assistant's value easier for everyone to see. Be aware that this is one line of work. The corpus doesn't have a set of studies breaking scarcity effects down by demographic group.

A related finding comes from voice shopping. People who looked at fewer alternatives through Alexa were more satisfied with their decisions and more willing to hand over control Does limiting product choices increase trust in voice assistants?. That reverses the usual pattern, where more options help people feel confident. Scarcity and a narrow choice set work in similar ways: both shrink the decision. When there is less to weigh, and possibly less time to weigh it, letting an agent act can feel like relief rather than a loss of control.

Where the corpus does show differences between consumers, the differences concern the terms of delegation rather than the conditions. Accenture's large survey found that most people say they would trust an agent with purchases, but many still want to choose the brand, and loyal customers resist switching Do consumers actually want to delegate shopping decisions to AI?. RTB House found that approving a purchase before it goes through is the safeguard people want most, and baby boomers want it most of all Do consumers want to approve AI shopping purchases before they happen?. That points to an open tension. Scarcity rewards speed, which is the main reason to use an autonomous assistant. Yet the consumers most cautious about delegating want a confirmation step that slows the agent down. The corpus doesn't test this collision, but it is the place where scarcity is most likely to split consumers.

There is also a twist on the agent side. When researchers changed price, rating, and nudge cues in matched ways, LLM shopping agents shifted their choices far more than humans did, and their choices became almost rule-like Do shopping agents respond more strongly to price and rating cues?. Scarcity messages like "only 2 left" are exactly this kind of cue. Consumers who adopt assistants because of scarcity may be handing their decisions to something that reacts to scarcity signals more strongly than they would. As agents increasingly decide which offers win attention Will agents compete for attention just like users do?, sellers have a clear reason to aim scarcity framing at the agent rather than the human.
