Sorry Susan, I really wanted this to work out!
I love the premise of the book: summarized scientific studies with practical tips on how to apply them in designs. But a little past the first third of this book I already knew it wasn't for me, so I started this list of 10 Things I Disliked About 100 Things Every Designer Needs to Know about People:
1. Most stuff is actually pretty obvious. You could just read the chapter titles and you'd have a good grasp of what the content is about.
2. The author keeps promoting her own other book "Neuro Web Design - What Makes Them Click", not 2 times, not 3 times, but dozens of times - the very proof of it is that I memorized that title.
3. The tone of voice is weird and inconsistent. It feels like the book is a mix-and-match of random notes the author took over years without proper care of how they'd fit together.
4. Most chapters are merely superficial summaries of a single study, without proper comparison with others that might have proved the contrary under a different light - you know, like scientists would do.
5. On a particular chapter, the author promotes a Psychology theory that she herself admits is polemic and not taught anymore on Psychology classes. I wonder how many other times it happens throughout the book without the proper disclaimer...
6. The author takes every study at face value and assumes its results are universal, so you MUST account for that in design. On top of that, the "Takeaways" section, instead of being a summary of the chapter, is actually where the author tells you how to apply that knowledge, without much further explanations.
7. On every chance possible the author tries to extrapolate the article results often committing logical fallacies. On a particular chapter about the bidirectional influence between emotions and facial expressions, she implies that if you have small text on your design this will make people frown when reading, and this will make them feel unhappy with any content they come up with next. Really?
8. Some chapters are just Neuroscience jargon filled brain parts names. There's even one full page of illustrations of them - like if it was of any use!
9. The visual design of the book is pretty awful. Like the little misaligned stars used as bullets, or some pages that have 1 paragraph of text and the rest is white space.
10. And, finally: it bothers me how this book very popular, often found in "must-read design books" lists, and even so highly rated here in this fine community of thoughtful readers. I don't get it.
Bonus: there are lots of references to U.S. culture without further contextualization, assuming the reader was from there too.
I'd rate it just 1 start, but it deserved an extra one because some chapters are actually OK (I particularly liked the chapter 66)
Update: rewrote some sentences to improve grammar - sorry, English is not my first language :)
