Based on prior knowledge, the workclass feature represents the employment status of an individual, which could have an impact on their income. By analyzing the relationship between the workclass feature and the target variable of earning more than $50,000 per year, we can create a dictionary with the relevant details.

```json
{
	"no": ["Private", "Local-gov", "?", "Self-emp-not-inc", "Federal-gov", "State-gov"], 
	"yes": ["Self-emp-inc"]
}
```

In this case, the "no" list includes possible workclass values for individuals who do not earn more than $50,000 per year, while the "yes" list includes the possible workclass values for individuals who do earn more than $50,000 per year.

Note that the "?" value is included in the "no" list as it represents missing or unknown values, which may be a factor in individuals not earning above the threshold.
