This morning I sent a report regarding a software issue.

Based on the logging and screenshot, I deduct this conclusion:

  1. some undefined error happened on the server side, which needs server dev to track
  2. the error code crashes the client application which needs client dev to add more error handling ...

Is it natural/common to say "deduct conclusion" in this context?

Ngram Viewer seems to indicate that nobody says it that way.

Try "deduce" instead of "deduct". The latter form usually means to subtract something. You would not usually say "deduce a conclusion", but rather "deduce this", or "come to this conclusion", or "arrive at this conclusion".

  • Thank you. Is it clear and natural to say "Based on the logging and screenshot, it comes to this conclusion ..."

  • No, "I come to this conclusion" would fit, meaning that a person has decided something based on evidence. "It comes to this conclusion" would mean that something (not a person) had stopped. Jul 12, 2020 at 12:12

I've personally never heard or seen "deduct conclusion" in written or oral communication. Some popular alternatives are "In conclusion", "To conclude", To summerize" or "The takeaway is".

  • The alternatives in the answer are really handy. Thank you. How do I make it a complete sentence in a formal setting? "Based on the logging and screenshot, to conclude" doesn't seems fluent.
