A new study has shown that exposure to a fishy smell can make people more suspicious, raising their level of critical thinking skills.

No one likes a fishy smell, but it may actually have a positive impact on people’s brains.


A recent study has found that it can improve critical thinking by arousing suspicion. 


To test the odor’s effect on cognitive abilities, researchers lightly sprayed an enclosed area with fish oil then asked the participants questions including, “How many animals of each kind did Moses take on the Ark?”
