Looking something up each time is not the same as understanding it

The argument

Opponents argue that the case for phones confuses access to information with the possession of knowledge. Knowing something, in any sense that matters for thinking, means having it integrated with everything else one knows: available for comparison, able to be noticed as relevant when it has not been asked for, and connected to the reasons that support it. Retrieval supplies none of this. A person who looks up a fact has the fact for as long as the screen is open and has acquired nothing that will combine with anything else, which is why the same lookup is performed again the following week. Opponents argue that this matters most for the judgements people actually need to make. Recognising that a claim is implausible, that two statements cannot both be true, that an argument has skipped a step, or that a question is the wrong one to ask all depend on having a body of knowledge in mind against which the new item can be compared. None of those operations can be performed by querying a device, because they require noticing that something is worth querying in the first place. A person who holds little and retrieves everything is therefore dependent on the quality of whatever the device returns, with no independent position from which to assess it. Opponents add that the sense of understanding the device produces is itself misleading. Having found a clear explanation, people reliably feel that they now know the subject, and they overestimate how much they could reconstruct without help. On this account phones do not merely fail to make people smarter; they make people worse at estimating what they know, which is a particularly costly form of ignorance because it removes the signal that would prompt someone to learn more.

Premises

Counter-arguments

Proponents reply that the standard being applied is one almost nobody met before phones either. Most people have always held a thin and poorly integrated stock of facts, misremembered much of it, and had no means of checking; the relevant comparison is with that, not with an idealised scholar. They argue that integration happens through use rather than through storage, and that someone who consults material repeatedly in the course of doing something is building exactly the connected understanding the argument describes. On overconfidence, proponents note that people have always overestimated what they know, and that a device which makes checking effortless gives them the readiest means yet of discovering they were wrong, if they choose to use it.

Rejecting the premises

[Rejecting P1] This sets a standard of integrated knowledge that few people met before these devices existed, so it cannot show that phones caused a decline. [Rejecting P2] Repeated consultation in the course of doing something does build connected understanding, so retrieval and integration are not opposed. [Rejecting P3] A person can hold the structure of a field while looking up its details, which is how most expert practice already works. [Rejecting C] Effortless checking gives people the readiest means yet of correcting what they wrongly believed they knew.
