I’m rewriting a system me and my friends are playing in to better suit what want. For the most part it’s gone over great but there is one thing that I am miffed about. They often mix two skills that are based off of different ability scores together and think they are too similar.

I would really appreciate getting some opinions. Thanks in advance.

Here is what I have written so far:
Investigation (Dex based sense roll)
“See the small details. Let nothing go unnoticed.”
Your ability to find small hidden details in varied chaotic environments and inferring further information from them. Be it hidden compartments or a concealed weapon, if they are hiding something out of sight, you’ll spot it.
Great for: Detectives, Scavengers, Spies.

Analyze (Int based sense roll)
“Analyze everything. Deduce the world.”
Your ability to parse and find details within readily available but dense information. Find someone hiding in a crowd, an anomaly in a data readout or calculate the trajectory of a projectile from the bullet hole. As long as the data is clear to you, you’ll find what stands out.
Great for: Analysts, Detectives, Forensic Scientists.
