To what extent is sense perception an accurate way of knowing?

Sense perception, i think is like a guide for us to make decisions, but not the one which gives the answer for the decision. However it is suprising to see people, keeping on depending on the sense perception to seek for answer.
I would like to say we seriously shouldn't fully depend on it. We have to make overall decision from our knowledge, using the evidence given by the sense perception. I feel like the life is like full of problem solving questions; to make sure we make the decisions right, sense perception should be used as a small guide/half broken compass (?).

First of all, we have to know sense perception, these sharpest tool of ours can even make mistakes. For example, the class was given a video and was told to count how many times people in white t-shirt were passing. From the video screen, there were few people wearing white and some wearing black t-shirts. One person from two teams was given a basket ball. Then the video started and all the people were starting to concerntrate on how many times people were passing the ball. After few minutes, the teacher stopped the video and asked the class first about the number of passes. Of course they were able to answer this first. However, the next question, they weren't able to answer. The next question from the teacher was 'what did you see also?'
Well, everybody was only concerntrating on the ball, so nobody was able to answer the question. So then the teacher replayed the video. Now all the people were able to understand the teacher's question. There was a gorrilla, it actually passed through the players and disappeared. It was so easy enough to see but nobody noticed it. It made the most of the students feel slight dumb as they didn't see the gorilla which was right in front of them. Therefore sense perception shouldn't be trusted fully.

However, even though, sense perception makes mistakes, but we still need them half fully. For example, there is a person driving a car and is using the map as the only source which tells the direction of the place. This person has no idea where the place is. However, the person knows that the map s/he is holding right now has some mistakes and because of the map s/he already had been lost few times .But without the map, the person will be having no idea of the place s/he is situated in. Therefore, the person has no choice but to use the map to get extra information about the place but decides not to fully believe it and uses it as a guide to make an overall decision by her/himself. Sense perception is like that map. Even though, it makes mistakes (makes wrong decisions), like the map, sense perception is the best source to support us from making an overall decision.

It is very suprising by the fact that our sense perception, our most reliable source even makes mistakes. It is very depressing to know that our last ever source even is unreliable. However, we still need them and is the best source for supporting us on making the best decision.
