Ipsos’ latest Perils of Perception study shows which key facts the online public1 across 37 countries get right about their society – and which they get wrong. Now in its fifth year, the survey aims to highlight how we’re wired to think in certain ways and how our environment influences our (mis)perceptions.

Crime

In several countries around the world, people are wrong about the scale of knife and gun crime in their country. Although in 13 countries the majority correctly guess which is the biggest killer out of firearms, sharp objects such as knives or other physical violence, in other countries people’s perceptions don’t match what the crime statistics say.

in their country. Although in 13 countries the majority correctly guess which is the biggest killer out of firearms, sharp objects such as knives or other physical violence, in other countries people’s perceptions don’t match what the crime statistics say. For example, in Great Britain, 71% of people think knives cause the most deaths , when they actually account for just 25% of all deaths by interpersonal violence. The GB guess for knives is the highest across all 37 countries surveyed, but there is a similar pattern of overestimating their impact in other countries, especially other European countries such as Denmark, Germany, Italy, Poland and Hungary, and in Asian countries such as Japan, South Korea, Singapore and China.

Other countries overestimate the proportion of gun deaths , notably South Africa (where knives cause the most deaths), Netherlands and Sweden. And even some countries where the scale of certain types of violence dwarf others, large minorities do not realise this. For example, in the US – where firearms account for almost 70% of all deaths through interpersonal violence, only six in ten (59%) correctly identify guns as the biggest killer, and a similar pattern is seen in Colombia.

People in most countries think prisons are even more crowded than they actually are. On average people think prisons are 30% over full capacity (130%) when they are 9% over capacity (109%). Having said that, the countries with the highest levels of overcrowding do tend to be the countries with the highest guesses.

Sexual harassment

In 13 countries for which there is data, all of them substantially underestimate women’s experience of sexual harassment in their nation. On average, people think 39% of women have experienced harassment, but actually on average 60% have. Denmark, the Netherlands, France and the United States are the most likely to underestimate the extent of sexual harassment in their country.

in their nation. On average, people think 39% of women have experienced harassment, but actually on average 60% have. Denmark, the Netherlands, France and the United States are the most likely to underestimate the extent of sexual harassment in their country. In each country, men give a lower estimate of sexual harassment than women. On average, men guess 36% of women in their country have experienced sexual harassment, but women’s guess is 44% (although still an underestimate).

Climate change

17 of the past 18 years have been the hottest since records began. However, every country in the study underestimates the global temperature rise over the past 18 years. The average estimate across the study was 9 years.

over the past 18 years. The average estimate across the study was 9 years. The majority of countries overestimate the amount of energy used that comes from renewable sources in their country. The average guess is 26% when it’s actually only 19%. Malaysia, Saudi Arabia, China and Singapore were the furthest out; some countries, though, actually underestimate how much progress they have made with renewables, such as Sweden and Montenegro.

Sex

Nineteen countries in the study include estimates for the amount of sex they think 18-29 year olds are having, and most of them get it very wrong . On average people think young women have sex 20 times every 4 weeks and the guess for men is slightly higher at 22 times . In fact, when asked in the survey, 18-29-year-old women and men report they have had sex 5 and 6 times every 4 weeks respectively.

. On average people think and the guess . In fact, when asked in the survey, 18-29-year-old women and men report they have had sex 5 and 6 times every 4 weeks respectively. People in Mexico, India, Brazil, Italy and Colombia are particularly far out in their estimates of how much sex young people are having . Sweden, Britain and Turkey have lower, slightly more realistic guesses.

. Sweden, Britain and Turkey have lower, slightly more realistic guesses. Across the study, there is little consistent difference in guesses by women and men. And young people themselves are only slightly less likely to overestimate how much sex their peers are having than older people (on average, under 30s guess that other 18-29 year olds are having sex 20 times a month, among over 30s the average guess is 21).

Vaccinations

All countries in the survey underestimate the near universal level of infant vaccinations in their country. The average guess is 73% when the actual figure is 94% according to World Health Organisation (WHO) figures. Furthest out are India, Mexico and China.

Economy

Every country in the study heavily overestimates the proportion of people unemployed and seeking work in their country. The average guess across the study was 5 times greater than the actual (34% when in reality it is closer to 7%).

in their country. The average guess across the study was 5 times greater than the actual (34% when in reality it is closer to 7%). People tend to underestimate the size of their country’s economy relative to others. The majority of people placed their country’s GDP rank lower than the reality. This is particularly the case for emerging economies such as Argentina, South Africa and Romania.

Population facts

Every country massively overestimates the levels of growth of their elderly population . Across the countries on average, people think 54% of the population will be 65+ in 2050 when in reality the projection is less than half that (25%).

The majority of countries hugely overestimate levels of immigration ; a pattern we have seen in previous studies. The average guess across 37 countries is that 28% are immigrants when the actual figure is less than half that (12%).

; a pattern we have seen in previous studies. The average guess across 37 countries is that 28% are immigrants when the actual figure is less than half that (12%). Nearly every country included in the study also over-estimates their Muslim population by a large margin. The average guess was more than double the actual figure (20% vs 8%).

How accurate is the British public…?

Seven in ten Brits (71%) think more people are killed by knives than firearms or other violence when in reality knives only account for 25% of all deaths across the three types of interpersonal violence.

when the actual figure is 108%. Britons underestimate women’s experience of sexual harassment. On average, we think half of British women have experienced sexual harassment since the age of 15, but in fact it is around two in three (68%).

On average, we think half of British women have experienced sexual harassment since the age of 15, but in fact it is around two in three (68%). When it comes to sex, Britons think 18-29 year olds have far steamier lives than they actually do . We think young women are having sex 13 times every 4 weeks when it is actually about once a week on average (4-5 times every 4 weeks). And Brits think 18-29-year-old men are having sex 14 times every 4 weeks, far higher than the actual average of 5.

And Brits think 18-29-year-old men are having sex 14 times every 4 weeks, far higher than the actual average of 5. Britons are too optimistic about the levels of energy consumed that comes from renewable sources. The average guess in Britain is 24% when it is actually just 9%.

against Diphtheria, Tetanus, Whooping Cough, Polio and Measles when levels are much higher at 94%. Levels of unemployment are hugely overestimated in Britain. People think one in five working age Brits are unemployed and looking for work (18%) when the actual figure is less than a quarter of that (4%).

when the actual figure is less than a quarter of that (4%). When it comes to gauging our economic place in the world, Britons are slightly too pessimistic, the average guess is that Britain is the 12th largest economy by GDP when in reality it is the 5th.

with an average guess of 24% when the actual figure is around half that (13%). In line with previous studies, Britons are very wrong about the percentage of Muslims in Britain. The average guess is more than four times the actual figure (17% vs the 4% reality).

But compared to other countries, Britons are more accurate than most – in fact we are the 5th most accurate country in our “Misperceptions Index” – above Denmark who have slipped down the rankings since last year.

Looking across seven key questions where we get people to estimate factual realities, there are clear patterns in which countries have a more accurate view of their countries. To capture this, we’ve calculated the Ipsos “Misperceptions Index”, as shown in the table below.

This year Thailand receives the unwelcome prize of ‘least accurate’ in their perceptions, closely followed by Mexico and Turkey.

Hong Kong is the most accurate, followed by New Zealand, with the ever accurate Swedes in third.

Gideon Skinner, Research Director at Ipsos MORI’s Social Research Institute said:

Ipsos’ global Perils of Perceptions study shows that, around the world, many people overestimate the real extent of some social issues, while underestimating the importance of others. Our latest research reveals that in many countries certain signal crimes really grab the public’s attention more than official statistics suggest they should. But on the other hand, on a major issue such as sexual harassment towards women, many people do not realise quite how prevalent it really is. Reflecting concerns since the financial crash, people overestimate the level of unemployment in their country, and are overly pessimistic about the relative size of their country’s economy, while perhaps are too complacent when it comes to climate change and the use of renewable energy sources. Not to mention, of course, wildly overestimating the amount of sex young people are having.

This applies just as much to Britain – even if other countries around the world are even further out in their misperceptions than we are. We are the most wrong when it comes to overestimating what proportion of violent deaths are due to knives, and like other countries overestimate prison overcrowding, unemployment and our use of renewable energy, while underestimating sexual harassment, how many children have been vaccinated, and the size of our economy – we think it’s 12th in the world, but actually we are fifth.

There are many different reasons why we may be wrong about various facts of society. These can include external influences on us, such as what we hear in the media or online, but our own internal biases are just as important. These biases include our tendencies to focus more on negative stories over positive ones, to believe that things were always better in the past, to put too much emphasis on our own individual experience, and simply not being very good with numbers. But what is crucial to understand is that we overestimate what we worry about as much as we worry about what we overestimate - in other words, misperceptions can be a very useful pointer to people's real concerns. It also means that trying to correct misperceptions by only repeating the facts is unlikely to work - instead we need to engage with the more emotional reasons that might be driving why people are worried about a topic.

Technical Note

These are the findings of the Ipsos MORI Perils of Perception Survey 2018. 28,115 interviews were conducted between 28th September – 16th October 2018.

The survey is conducted in 37 countries around the world, via the Ipsos Online Panel system in Argentina, Australia, Belgium, Brazil, Canada, Chile, China, Colombia, Denmark, France, Germany, Great Britain, Hong Kong (SAR, China), Hungary, India, Italy, Japan, Malaysia, Mexico, Netherlands, New Zealand, Peru, Poland, Romania, Russia, Saudi Arabia, Singapore, South Africa, South Korea, Spain, Sweden, Switzerland, Thailand, Turkey and the USA. The following countries used either online or face-to-face methodologies: Montenegro, Serbia.

Approximately 1000 individuals aged 16-64 or 18-64 were surveyed in Australia, Brazil, Canada, China, France, Germany, Great Britain, Hong Kong, India, Italy, Mexico, Montenegro, Serbia, Singapore, Spain and the USA. Approximately 2000 individuals aged 16-64 were surveyed in Japan. Approximately 500 individuals aged 16-64 were surveyed in Argentina, Belgium, Chile, Colombia, Denmark, Hungary, Malaysia, Netherlands, New Zealand, Peru, Poland, Romania, Russia, Saudi Arabia, South Africa, South Korea, Sweden, Switzerland, Thailand and Turkey.

21 of the 37 countries surveyed online generate nationally representative samples in their countries (Argentina, Australia, Belgium, Canada, Denmark, France, Germany, Great Britain, Hong Kong (SAR, China), Hungary, Italy, Japan, Netherlands, New Zealand, Poland, Singapore, South Korea, Spain, Sweden, Switzerland, and United States).

Brazil, Colombia, China, Chile, India, Malaysia, Mexico, Peru, Romania, Russia, Saudi Arabia, Serbia, South Africa, Thailand and Turkey produce a national sample that is more urban & educated, and with higher incomes than their fellow citizens. We refer to these respondents as “Upper Deck Consumer Citizens”. They are not nationally representative of their country.

The “actual” data for each question is taken from a variety of verified sources. The most recent available data has been used which in most cases is from the past two years. Figures for sexual harassment are largely from a 2012 study for the EU Fundamental Rights Agency and some country data for the Muslim population is from pre-2015. A full list of sources/links to the actual data can be found below.

Where results do not sum to 100 or the ‘difference’ appears to be+-1 more/less than the actual, this may be due to rounding, multiple responses or the exclusion of don't knows or not stated responses.

Data are weighted to match the profile of the population.
