Every industry has a reputation. It's not easy to define since it includes lots of qualitative factors such as customer service, product innovation, transparency, regulatory compliance, and even corporate citizenship.

There is an annual report called the Global Corporate Reputation Index that ranks the main industries. The oil and banking industries are at the bottom of the list, whereas technology is at the top (perhaps the main reason is that the industry launches innovative products that can greatly enhance people's lives).

Then there are some surprises. For example, the auto industry has an overall strong reputation as there have been strong improvements in reliability and quality.

Now, this does not mean you should avoid an industry that has an average reputation. Keep in mind that companies in the oil and gas industries have grown substantially over the years. This trend will probably continue.

Rather, reputation is likely to be more of a personal consideration...
