Driven by data; ridden with liberty.
Another reason for data misinterpretation is to generate headlines. The Sun newspaper managed to stoke controversy  by claiming on the front of their Monday 23rd November edition that a “shock poll” found:
1 in 5 Brit Muslims’ sympathy for jihadis.
The photo caption read:
Support… Brit Jihadi John who went to Syria.
The front page highlighted a Kelvin McKenzie article, suggesting:
Time for Britain to shut door.
The Times, which is also owned by The Sun’s parent company News International, also had a headline : “One in five British Muslims has sympathy for Isis”.
Polling was conducted by Survation , of 1,003 adult Muslims in Great Britain, who were asked questions related to their faith, and to terrorism. Respondents were asked which was closest to their view:
I have a lot of sympathy with young Muslims who leave the UK to join fighters in Syria;
I have some sympathy with young Muslims who leave the UK to join fighters in Syria;
I have no sympathy with young Muslims who leave the UK to join fighters in Syria.
Whilst other questions in the poll did refer to ISIS, or the Islamic State, this question did not, nor did it refer to “jihadis”. In addition, sympathy is a distinct stance from support.
In the November poll, 5% of British Muslims said they have “a lot of sympathy with young Muslims who leave the UK to join fighters in Syria”, with a further 15% responding they have “some sympathy”. 71% said they have “no sympathy”.
Survation polled British Muslims  and non-Muslims  in March 2015, on behalf of Sky News, which is also owned by News International. In the March poll, 61% of respondents described having “no sympathy with young Muslims who leave the UK to join fighters in Syria”. Furthermore, 8% of those surveyed said they had “a lot” of sympathy, and 20% saying they had “some sympathy”.
The Survation poll of non-Muslims in March 2015 is useful for a comparison. 4% of non-Muslims shared the view of “a lot of sympathy”, and 9% said they had “some sympathy” with those young Muslims joining fighters in Syria. This suggests that, on this particular issue, there is a similarity in belief between Muslims and non-Muslims: an overwhelming majority show no sympathy towards those Muslims seeking to compete in Syria’s battle royal.
It was unfortunate that The Sun did not fund the equivalent poll of non-Muslims, to allow a full and proper comparison with Survation’s March survey. Indeed, November’s poll by Survation demonstrates a fall in any sympathies towards young Muslims wanting to leave the United Kingdom in order to join Syrian combatants.
It was not a “shock poll”: it was a misinterpretation seeking a headline.
