Who is the Prejudice poster for?
Prejudice belongs to the Psychology section rather than to a school year, because life science is not something one grade owns. Anyone learning social can pin it up — a beginner, a student mid-course, or someone revising years later.
When should you use the Prejudice poster?
Contact alone does not reduce prejudice. Four conditions have to be met. A wall chart earns its place by being glanceable from where the work is happening, so Prejudice belongs on the wall where that life science work actually happens, within glancing distance, rather than filed away.
What other posters go with Prejudice?
Helping Behaviour, Attitudes & Behaviour and Attribution sit alongside Prejudice in the Psychology section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Helping BehaviourAttitudes & BehaviourAttribution
Is the Prejudice poster free to download and print?
Yes. Prejudice downloads as a free PDF with no account, no email and no watermark, like everything else in the Psychology section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
What size does the Prejudice poster print at?
Prejudice is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Prejudice loses nothing.Printing guide
