Does this book give any ways to avoid being predictably irrational, or is it just pointing out our flawed thinking. In other words, is it hopeful or pessimistic?

In the same way that writing down everything you eat will force you to think about your food intake and affect your eating choices — learning about behavioral tendencies will help you make conscience rational decisions (or at least be aware of the irrational decisions you make).

This will depend on your own cost/benefits assessments for these decisions — meaning, once you are aware of a particular tendency, you will have to decide:
1. How much does it bother you?
2. How much effort will it take to change? (What will it cost you?)
3. How motivated are you to make that effort? &
4. What benefits (& detriments) will result from changing? (pro/con)
Collectively: Is it worth it to you?

Once you identify an irrational behavior in your life, if you decide it's worth the effort to change, you will, and if it's not worth it, you won't. But at least you'll know why.(less)
