Cognitive Biases in Car Buying

Sunk-Cost Fallacy: Feeling like you need to buy the car because you’ve already spent so much time at the dealership.
Anchoring Bias: Getting stuck on the first price you hear and letting it shape all your other decisions.
Confirmation Bias: Only paying attention to information that supports your desire to buy the car you want.
Availability Heuristic: Basing your decision on a recent story or experience, like a friend’s good or bad deal, rather than the full picture.

FAQs for Installing R, RStudio, and TinyTeX

@ Kellogg School of Management

1. `/usr/local/bin` not writable

I see this error when I install TinyTeX:

add_link_dir_dir: destination /usr/local/bin not writable, no links from /Users/hagen/Library/TinyTeX/bin/x86_64-darwin. add of symlinks had 1 error(s), see messages above. add of symlinks had 1 error(s), see messages above. tlmgr: An error has occurred. See above messages. Exiting.

This is an issue on some Macs, where that folder /usr/local/bin is not writable by your user account for some reason. Here's how to fix it:
