The majority of people do not trust computers to make decisions about any aspect of their lives, according to a new survey.
Over half (53%) of UK adults have no faith in any organisation to use algorithms when making judgements about them, in issues ranging from education to welfare decisions, according to the poll for BCS, The Chartered Institute for IT.
The survey was conducted in the wake of the UK exams crisis where an algorithm that was used to assign grades was scrapped in favour of teachers’ predictions.
Just 7% of respondents trusted algorithms to be used by the education sector - joint lowest with social services and the armed forces. Confidence in the use of algorithms in education also differed dramatically between the age groups - amongst 18-24-year-olds, 16% trusted their use, while it was only 5% of over 55-year-olds.
Distrust of social media
Trust in social media companies’ algorithms to serve content and direct user experience was similar at 8%. Automated decision making had the highest trust when it came to the NHS (17%), followed by financial services (16%) and intelligence agencies (12%), reflecting areas like medical diagnosis, credit scoring and national security.
Police and ‘Big Tech’ companies (like Apple and Google) were level with 11% of respondents having faith in how algorithms are used to make decisions about them personally.

Older people are less trusting about the general use of algorithms in public life, with 63% of over-55s saying they felt negative about this, compared with 42% of 18-24-year-olds. Attitudes to computerized decisions in the NHS, private health care and local councils differ very strongly by age. 30% of 18-24-year-olds said they trusted the use of algorithms in these sectors, while for those over 55, it was 14%.
Over 2,000 people responded to the survey conducted by YouGov. All were shown a description of algorithms before answering any questions.
Algorithms used in daily life - but still misunderstood
‘People get that Netflix and the like use algorithms to offer up film choices, but they might not realise that more and more algorithms decide whether we’ll be offered a job interview, or by our employers to decide whether we’re working hard enough, or even whether we might be a suspicious person needing to be monitored by security services.
‘The problem government and business face are balancing people’s expectations of instant decisions, on something like credit for a sofa, with fairness and accounting for the individual, when it comes to life-changing moments like receiving exam grades.
‘That’s why we need a professionalised data science industry, independent impact assessments wherever algorithms are used in making high-stakes judgements about people’s lives, and a better understanding of AI and algorithms by the policymakers who give them sign-off.’
UK National variations
Wales has the highest percentage of people who do not understand how algorithms are used in daily life, such as credit scoring or benefit claims decisions. The region scored 20% in the ‘do not understand at all’ response compared with the UK average of 14%. Wales is also the most distrustful of all the devolved nations when it comes to algorithms that affect them personally, at 57%. The UK average is 53%.
Scotland is the most trustful of all the devolved nations when it comes to algorithms that affect them personally, with 48% saying they don’t trust any organisations to use algorithms to make decisions about them - compared with a UK average of 53%. It also has the lowest percentage, at 6%, of people who know nothing about how algorithms are used in daily life.
Northern Ireland is the most positive of the devolved nations about how algorithms can be used to make decisions about public life, at 45% negative, compared with an average of 56% across the UK. It also has the highest level of trust in social services using algorithms to make decisions about them personally, at 13% compared to the UK average of 7%.
