An earlier generation of careful people relied on a small number of habits to maintain a private life. They did not give interviews. They did not seek attention. They did not appear in directories that did not require them to. They were known to those they did business with, and largely unknown to those they did not.

These habits produced a private life, in their time, because the systems that could otherwise have assembled the principal's affairs did not exist. The records were scattered; the work of joining them was the work of a journalist or a private investigator and was slow, expensive, and uncertain. The default of doing nothing produced a real protection.

The default has changed. The records are now assembled automatically. The work that would once have required a person with a reason to enquire is now performed routinely against anyone with a profile. The principal who keeps quiet today is not, by quietness alone, protected. They are, in many cases, leaving the assembly to be done by parties whose interests are not aligned with their own.

The new habits are not louder or more public. They are more particular. They involve knowing what the assembled record currently says about the principal. They involve correcting what is wrong about that record, in the places where correction is available. They involve a continuing audit of how the principal's information moves through the systems they engage with, and where it leaks into systems they do not.

Older habits of privacy have not become useless. Discretion remains the foundation of any considered approach. But discretion is no longer, by itself, sufficient. It must be paired with an active management of a record that, increasingly, is constructed without the principal's participation.
