And that’s most people, right?”Van Toorn added that machine learning also had a “black box” problem – in which it is hard for humans to know which data points the machine is using, what weight it is giving to them and what biases it is assuming – as it learns and makes decisions.“I think there’s an assumption that because it’s data-driven, it’s accurate and personalised … But in this case, I think that the crucial part is the human in the loop needs to understand the limitations [of the technology] … and exercise their discretion and judgment.skip past newsletter promotionafter newsletter promotion“And they need to be properly trained and supported to do so at the right moment.”Van Toorn said the fact the NDIA documents explicitly state that decisions on support plans are made by humans was important.However, she cautioned that there is a lot of evidence for what researchers call “automation bias” – where people are influenced by AI recommendations when making decisions.“There might be time constraints or pressures on planners to get through a certain amount of plans to meet KPIs, or there might be pressures on the NDIA generally to be reducing the number or cost of plans,” she said.“The risk is that if it makes their job quicker or easier, a planner might be more likely to go along with the recommended plan, leaning on the algorithm instead of using their own judgment or really listening to NDIS participants.”View image in fullscreen‘These things are so serious and so significant’ … disability advocate Stevie Lang HowsonDr Stevie Lang Howson, an NDIS participant and disability advocate, said his “biggest concern” was whether staff were trained, equipped and given time to “meaningfully make our plans suit our needs as individuals”.“These are actually people’s lives. They’re how many times people are able to get to the bathroom … it’s how often you’re able to leave our house, it’s whether the wheelchair that you’re sitting in is too small and causes you pain … These things are so serious and so significant they need to be made with care and transparency and in a way that reflects people’s individual needs.”A spokesperson for the NDIA said AI was not used in systems “that interact directly with participants or providers or for any decisions on NDIS funding or eligibility”.“Delegates make decisions on a participant’s NDIS funding using information and evidence provided by participants in accordance with the NDIS Act,” the spokesperson said.The federal government on Wednesday released a whole-of-governmentAI plan for use of generative AI in the public service. The finance minister, Katy Gallagher, said the plan would give every public servant access to generative AI tools, training and guidance on how to use the tools safely and responsibly.Explore more on these topicsNational disability insurance schemeAustralian politicsArtificial intelligence (AI)MicrosoftnewsShareReuse this content
