Being 'radically different' in branding and marketing can have several potential pitfalls. It can lead to confusion among consumers if the brand's message is not clear or consistent. It can also alienate existing customers who are used to a certain image or message from the brand. Furthermore, being too different can make it difficult for the brand to fit into established market categories, which can hinder recognition and recall. Lastly, it can be risky if the difference is not well-received by the target audience, leading to a negative perception of the brand.
