AI can make us feel faster without actually making us faster.
There is now a name for it: The Speedup Illusion.
A fascinating new preregistered study involving 1,237 participants found that people expected AI to make them significantly faster across a range of cognitive tasks.
For many of the tasks, it didn't.
What AI did change was how the work felt. Participants experienced it as less mentally effortful.
I find that distinction fascinating because it raises a much bigger question about our relationship with artificial intelligence.
If thinking feels easier, do we automatically assume we're becoming more efficient? And if we feel more efficient, might we also begin to assume that the quality of our thinking has improved?
Recent research into cognitive offloading raises another distinction that I think may become increasingly important:
Offloading cognitive labour is not the same as offloading cognitive authority.
AI can summarise, compare, calculate, generate alternatives and challenge our assumptions while we remain responsible for interpreting and integrating what it gives us.
Something different begins to happen when AI starts framing the problem, determining what matters, selecting the alternatives and recommending the conclusion.
The human may still press the final button.
But who actually organised the thinking that led there?
I've explored the research, the speedup illusion and what this could mean for human judgement and Coherence in my latest Psychernetics article:
