Example of a bad scientific poster

When I give lectures on poster design, I show examples of horrific posters I’ve found on the internet. But I fear that someday the author of a poster I’m critiquing is going to be in the audience and carrying a concealed weapon, so I thought it was time to construct my own bad poster. The result is, “Pigs in space: effect of zero gravity and ad libitum feeding on weight gain in Cavia porcellus.” A list of why the poster is awful is below the image.

I encourage teachers to print the poster and hang in a hallway a month prior to when students’ posters are due. Here’s the PDF. Ideally, also print and hang my poster that shows tips on how to make a poster. More poster tips than you really need, plus free templates, at “Designing conference posters“.

Why this is a terrible poster

  1. Too much text (I’ve been on mission to push for 800 words).
  2. Background image is distracting (distracts from illustrations).
  3. Text box backgrounds are dark, which makes text really hard to read.
  4. Text box backgrounds are all different colors, for no reason (distracting).
  5. Text boxes are different widths (distracting, hard to follow flow of poster).
  6. Some text boxes too wide (aim for 45-65 characters per line).
  7. Text boxes not separated from each other by pleasing “white” space.
  8. Text box edges not aligned (distracting).
  9. Text justified, which causes bad inter-word spacing. Also makes reading harder (brain uses jaggedness of left-justified text).
  10. Logos are distracting, useless, crowd title.
  11. Title word art distracting, hard to read, juvenile.
  12. Title is in all caps, which is harder to read and obscures Latin name.
  13. Title is italicized, which also obscures Latin name style conventions.
  14. Author font and color is annoying (comic sans should be reserved for comic books).
  15. Author font color is too loud relative to other text.
  16. Results are presented in sentences instead of visually with charts.
  17. Section headers have too much formatting (big font, bolded, italicized, underlined, and colored — ack!).  Choose one. [Note: I forgot to number the sections…that would have been even worse.]
  18. Terrible graphic of Guinea pig on scale. Need one of the actual set up (pigs eating while weightless, for example).
  19. Inclusion of an Abstract consumes space needlessly. Abstract section should be banned from posters. Posters ARE an abstract.
  20. Plus the science is terrible! (Bad science is correlated with bad graphic design, by the way.)

This poster was published in the journal Nature. And yes, that street number is a horrific gravity reference. Sorry.

Skunk cabbages in snow

Photograph of Eastern skunk cabbage (Symplocarpus foetidus) covered with snow.  I didn’t confirm with a thermometer, but these are famous for heating themselves up, maintaining 35 °C (95 °F) internal temperature even when outside air is below freezing.  Heat helps volatilize the awful smell, which can be attractive to flies and beetles, but also creates a hot “room” inside the curved leaf (spathe) that surrounds the inflorescence on the spadix (hidden from view at this angle).  But a more likely hypothesis of why this ability evolved is that thermoregulation protects pollen tube growth and female reproductive structures from frost damage. Either way, one of my favorite plants. Growing in the Crum Woods, Swarthmore, Pennsylvania.
