My Lords, it is a pleasure to follow the noble Lord, Lord Bassam, who has already set out very clearly what the group is about. I will chiefly confine myself to speaking to my Amendment 38A, which seeks to put in the Bill a clear idea of what having a human in the loop actually means. We need to have a human in the loop to ensure that a human interpreted, assessed and, perhaps most crucially, was able to intervene in the decision and any information on which it is based.
Noble Lords will be aware of many situations that have already arisen in which artificial intelligence is used—I would say that what we are currently describing is artificial intelligence but, in real terms, it is not truly that at all. What we have is a very large use of big data
and, as the noble Lord, Lord Bassam, said, big data can be a very useful and powerful tool to be used for many positive purposes. However, we know that the quality of decision-making often depends on the quality of the data going in. A human is able to see whether something looks astray or wrong; there is a kind of intelligence that humans apply to this, which machines simply do not have the capacity for.
I pay credit to Justice, the law reform and human rights organisation which produced an excellent briefing on the issues around Clause 14. It asserts that, as it is currently written, it inadequately protects individuals from automated harm.
The noble Lord, Lord Bassam, referred to the Horizon case in the UK; that is the obvious example but, while we may think of some of the most vulnerable people in the UK, the Robodebt case in Australia is another case where crunching big data, and then crunching down on individuals, had truly awful outcomes. We know that there is a real risk of unfairness and discrimination in the use of these kinds of tools. I note that the UK has signed the Bletchley declaration, which says that
“AI should be designed, developed, deployed, and used, in a manner that is … human-centric, trustworthy and responsible”.
I focus particularly on “human-centric”: human beings can sympathise with and understand other human beings in a way that big data simply does not.
I draw a parallel with something covered by a special Select Committee of your Lordships’ House, last year: lethal autonomous weapon systems, or so-called killer robots. This is an obvious example of where there is a very strong argument for having a human in the loop, as the terminology goes. From the last I understood and heard about this, I am afraid that the UK Government are not fully committed to a human in the loop in the case of killer robots, but I hope that we get to that point.
When we talk about how humans’ data is used and managed, we are also talking about situations that are—almost equally—life and death: whether people get a benefit, whether they are fairly treated and whether they do not suddenly disappear off the system. Only this morning, I was reading a case study of a woman aged over 80, highlighting how she had been through multiple government departments, but could not get her national insurance number. Without a national insurance number, she could not get the pension to which she was entitled. If there is no human in the loop to cut through those kinds of situations, there is a real risk that people will find themselves just going around and around machines—a circumstance with which we are personally all too familiar, I am sure. My amendment is an attempt to put a real explanation in the Bill for having that human in the loop.
