Specific CRM training was introduced around 30 years ago. The initial idea was to ensure the quieter amongst the crew stood up and made themselves heard, whilst simultaneously getting some of the more dictatorial to accept their input. Worth noting that the dictators were not necessarily the most senior. The concept of ensuring that as Captain, you used all the resources available to you, by default, really meant at least listening to input.
Like everything, it also swung too far at times. A coughpit is not a democracy. The buck has to stop with one seat only. But, as long as it's a benign dictatorship, then it will work.
There are events that just must be dealt with immediately. Then you issue orders. But, as soon as possible, you back up, and get the other(s) to go over what's been done, and look for any missed alternatives. That remains inclusive, whilst covering the immediacy of some events. For more day to day items, it often works well to do it in reverse. Hear everyone one else's ideas first...chances are you'll never need to put up your own!
Interestingly, there's an Australian characteristic that is generally a negative, but which can help in the coughpit. The tall poppy syndrome isn't normally viewed in positive way, but I think it makes it easier for Australian crews to speak up, and also easier for the senior to listen.
