Abstract

The Computers Are Social Actors (CASA) theory is the most important theoretical contribution that has shaped the field of human–computer interaction. The theory states that humans interact with computers as if they are human, and is the cornerstone on which all social human–machine communication (e.g., chatbots, robots, virtual agents) are designed. However, the theory itself dates back to the early 1990s, and, since then, technology and its place in society has evolved and changed drastically. Here we show, via a direct replication of the original study, that participants no longer interact with desktop computers as if they are human. This suggests that the CASA Theory may only work for emergent technology, an important concept that needs to be taken into account when designing and researching human–computer interaction.

Was the original paper ever replicated? Cause if not, that’s too strong a conclusion. A simpler explanation could be that the original paper got something wrong and wasn’t replicable.

"This suggests that the CASA Theory may only work for emergent technology[..]"

I think we can see this unfold in real time with large language model based chatbots like ChatGPT. First they seem almost human and the initial reaction is to treat them like that. Always say "Thank you!" and potentially get angry at them for being wrong. It doesn't take long though, to realize that the bot is a bot and even if it speaks human language it behaves significantly different from a real human. Then the human behavior starts to change as well and the bot is treated differently.

Except we see to see behaviors in asking questions to LLMs where we get different/better responses if we ask "please".

Wonder whether 1.) technical proficiency and 2.) age of introduction to computer would make a difference

Because totally anecdotally, I mean it could have been subconscious, but I never remember treating a computer that way. It’s always been… I dunno, a machine.
