BBC World Service - The Thought Show, Numbers of the Year 2015 – Part 1

More Or less looks back at some of the most interesting numbers of the year.

More Or less looks back at some of the most interesting numbers of the year, BBC Trending revisits the fuss over the colour of a dress and the Why Factor looks at group think.

In More or Less Tim Harford looks back at some of the most interesting numbers in the news in 2015. He investigates how the migrant crisis has affected the number of people seeking asylum, talking  to Leonard Doyle from the International Organisation for Migration and Clare Melamed from the Overseas Development Institute. 
In BBC Trending Anne-Marie Tomchak talks us through some of her favourite viral songs of the year. And we revisit one of this year’s biggest talking point - #thedress. People around the world debated which colour it was - dark blue & black or white & gold. Was discussing the dress a fuss over nothing, or did we learn something valuable in the process?
In the Why Factor, Mike Williams looks at the phenomenon of 'Groupthink'. He asks why we succumb to it, and how we can fight the urge to follow the crowd when voicing dissent might avoid dangerous consequences.
