Could Lego be trying to poison our children’s minds, turning them into their own personal Lego angry army?

A new study out of the University of Canterbury’s Human Interface Technology Lab examined how Legos influence children during a vital emotional development stage: their playtimes. Statistically speaking, there's an average of 75 Lego blocks for every person alive, so a study of this specific toy is quite relevant. Led by Christoph Bartneck, the team examined over 3,600 Lego figures dating from 1975 to 2010. They then had each face ranked by an outside group, Amazon's Mechanical Turk, to create emotion rankings based on the display on the figure. "Happy" faces triumphed, with "angry" close on its heels. Bartneck then looked at historical trends that shows the angry faces on the rise, especially with the battle and war themed sets increasingly offered from the toy manufacturer.

What does this all mean? With anger and fear on the rise in our Legos' faces, as well as more conflict based themes full of weapons, there’s a concern that children will mature and associate negative emotions with their memories of childhood playtime. [via Wired]
