Why are we so bad at estimating our time?

I am looking for informed opinions and articles on why we are so bad at estimating our time on projects, specifically from an IT project management-perspective.

I feel like it's a big joke, like 90% of all projects ever completed have gone over time and budget. And if they don't, they often are rushed, poorly done, or drive people mad working on it.
I am a data scientist working in an IT-focused division of a major financial company. My division is particularly bad at estimating timelines for our projects. I've been tasked to gather data and try to figure out the main factors involved, such as use of new technologies, number of people involved across different divisions, or maybe even the ratio of PMs to developers on a given project.
As a first step, I'd like to figure out: What the current thinking on this question among IT-management folks? I have a good list of data I want to gather, but want to make sure I'm covering all the bases.
Why are we bad at estimating time in general? Why are we bad at estimating time as a group? From a project management perspective? From an IT perspective? I've been trying to search for weighty, possibly academic, articles about this question, but all I am coming across are fluffy self-help type articles. On a general basis, this seems like a behavioral economics question, but I am interested in this from an IT-department perspective.
Thanks in advance for your help!
