Happens too often. Especially in group projects or critiques where you suggest an idea and they argue against it but still use it. Without giving you credit of course. It's all good though. Part of the creative process I guess. Never take anything to heart.
This is because as human,we think alike and wish for so many similar things and when you think you have finished thinking and you realised another person has executed your thoughts. Well, that's in a way
Also, it can also happen in a group work where there is no team spirit, especially when it is only one person working,the other may take the glory of the victory and then,you feel cheated because others have little or no contribution to the victory✌️
Alexander, Happens very often. And equally in social, academic and corporate settings. For example, every answer that others have posted are ones that I wanted to say. In comparison this is a poor example. However, we all need to give voice to our ideas. Publishing, exhibitions require support and some courage. Not necessarily things we all possess. I've found it helps to think ahead and plan the information you need to obtain and pass on to others to get the position or recognization you'd like to receive. Like a form of small and ongoing "advertisements" for yourself.
Every idea we contribute, whether credited to us or not, is a step towards personal and professional growth. It's a testament to our creativity and problem-solving skills. When we are generous with our ideas and not overly concerned with personal credit, it can strengthen team relationships and build trust. Being seen as a collaborative team player can have long-term career benefits.
Are we ever the 'owner' of a bright idea? 'It takes a village to raise a child', M. Mead said. Moreover, brainstorming is a questionable technique regarding its effectiveness. The gap between ideas and their implementation remains great. It is better to experiment, make a step, observe, learn, and act again, based on powerful questions. An HBR study showed that the companies that made a difference between ideas and their implentation have a automatic bias towards less return.
