I agree with much of this, but one underplayed trade-off is how linking data across government services reduces individuals' control over their own information. This can create murky trade-offs and unintended consequences.

To give one example: I know of a public sector organisation in the health field that went all-in on 'one person, one record'. Superficially, this made a lot of sense, as it makes contextualisation much easier if you can see every interaction an individual has had with the organisation in a single list.

EXCEPT - that's not really how life works. If you, as a journalist, contact that organisation, then should that professional query really be stored alongside your personal medical data? Similar things apply to other professionals, say a headteacher contacting the service for advice about a pupil. I think most people would have a reasonable expectation of a 'firewall' between personal and professional interactions, but this was not how the system worked. This led to a load of workarounds - inventing people called Mr James O'Malley Query About the PAF, for example - that made the underlying data much worse.

Your example of not having to update multiple Google services illustrates this further. Many people have multiple Google accounts to keep their personal and professional lives separate, and they reasonably expect to update each one separately. But when the government ties all interactions to a single identity, that separation becomes impossible.

"Tell us once" can quickly morph into "tell the entire state at once" - and this isn't necessarily desirable. For example, we offer free tuberculosis treatment to everyone, regardless of whether they are entitled to NHS care, because this is the best way to protect the public. This means that there will be people in the country illegally who are sharing personal information, like their address, with the NHS. If we link that data up with the Home Office, the net effect is to prevent people from accessing treatment for an infectious disease and thereby increasing the risk to the public.

Similarly, you might register a particular, private, phone number for your interactions with services where you need a reasonable expectation of privacy - for example, if you're reporting a safeguarding concern about a member of your family. Disaster might follow if all of your different phone numbers just get thrown into a single identity - or, more likely, services find work arounds and store phone numbers in unexpected places which exacerbate the problem the data sharing tries to solve - because it becomes very difficult for anyone to reliably update all of their data, even with a single service.

So, yes - there are a lot of good ideas in here, and the direction of travel is probably right. But it’s an area that needs careful thought and planning, as these kinds of changes often have unintended consequences—especially for the most vulnerable in society. We need to be open about the fact that ‘convenience’ often comes at the cost of personal control over data. This trade-off might sometimes be justified, but it deserves far more scrutiny than it currently receives.

This is such an excellent explainer, and filled various gaps in my knowledge of how we got to here. Thank you James.
