Forgetting used to be the default and now it has to be requested

What follows is an argument about default forgetting, and about where the received version of it stops being true.

Decay was the baseline condition

Paper burns, rots, gets thrown away in house clearances, and most of what any person ever wrote has always been lost. Social memory of an individual's mistakes faded because the people who remembered moved away or died. That decay was not a failure of the system; it was the property that allowed people to change and be treated as changed.

A society in which nothing is forgotten has never previously existed, so nobody has evidence about how one behaves.

The default flipped without a decision

Digital records persist by default because copying costs nothing and deletion requires action across every copy. Backups, caches, archives and third-party copies mean that even deliberate deletion is frequently incomplete.

For a while, nobody chose permanence as a social policy; it arrived as a property of the storage medium. The most consequential features of a technology are usually the ones nobody argued about.

Legal erasure rights exist and are limited

Some jurisdictions grant individuals a right to have certain personal data erased or delisted from search results under defined conditions. These rights are balanced against freedom of expression, public interest and the record-keeping needs of institutions, and they apply unevenly across borders. Delisting a search result does not remove the underlying material, which is a distinction frequently missed in reporting.

Look closer and anyone considering such a request should check the rules that apply where they live, since the differences are substantial.

Young people carry a record older generations did not

Material created at fifteen and retained indefinitely is a genuinely new condition, and the long-term effects are not yet known. Some jurisdictions have introduced specific protections for data collected from children, with varying scope. The concern is often framed around employment and reputation, and the evidence about actual consequences remains thin.

It is a change everyone can describe and nobody can yet measure.

Institutions forget selectively

Retention schedules, spent conviction rules and statutes of limitation are all deliberate, negotiated forms of forgetting built into legal systems. These exist because societies concluded that permanent records of certain things do more harm than good.

Look closer and digital retention frequently outlasts the formal rules, because copies persist in systems the rules did not anticipate. Policy forgetting and technical forgetting have come apart, and the gap is where most disputes now sit.

Personal forgetting is not the same thing

Human memory reconstructs rather than retrieves, and forgetting is an active and functional part of that process rather than a defect. Preserving external records does not preserve memory, and in some circumstances appears to substitute for it.

For a while, the two systems are being conflated in most public discussion of this subject. A perfect archive and a good memory turn out to be very different things to have.

The takeaway

Every society before this one forgot almost everything by default. We are the first to have to ask for it, and to be told no.

What replaced it works. That is not the same as it being nothing.
