any welcome. also, don't know jquery , i'm sure can done using js answers if could.

your if statements bit off. have elements looking for, no need them again,

here's fixed example:

function strengthcheckbox()  {  	var strengthcheckyes=document.getelementbyid("strengthcheckyes");  	var strengthcheckno=document.getelementbyid("strengthcheckno");    	if(strengthcheckyes.checked && !strengthcheckno.checked)  	{  		document.getelementbyid("checkboxstrengthresponse").value="you wrestled putin in past life didn't you?";  	}  	else if(strengthcheckno.checked && !strengthcheckyes.checked)  	{  		document.getelementbyid("checkboxstrengthresponse").value="that problem sometime in future";	  	}  	else if((strengthcheckyes.checked) && (strengthcheckno.checked))  	{  		document.getelementbyid("checkboxstrengthresponse").value="so it? yes or no? stop playing around!";	  	}  };
<thead>  			<th colspan="3">checkbox version</th>  		</thead>  		<tbody>  			<tr>  				<td><p>question</p></td>  				<td><p>answer</p></td>  				<td><p>my response</p></td>  			</tr>  			<tr>  				<td><p>can fight bare hands?</p></td>  				<td><input type="checkbox" id="strengthcheckyes" onchange="strengthcheckbox()">yes</input>  					<input type="checkbox" id="strengthcheckno" onchange="strengthcheckbox()">no</input>  				</td>  				<td><input type="text" id="checkboxstrengthresponse" size="60px" disabled></input></td>  			</tr>  			<tr>  				<td><p>are able outrun flying car?</p></td>  				<td><input type="checkbox" id="speedcheckyes" onchange="speedcheckbox()">yes</input>  					<input type="checkbox" id="speedcheckno" onchange="speedcheckbox()">no</input></td>  				<td><input type="text" id="checkboxspeedresponse" size="60px" disabled></input></td>  			</tr>  			<tr>  				<td><p>can out play super ai in chess?</p></td>  				<td><input type="checkbox" id="intelligencecheckyes" onchange="intelligencecheckbox()">yes</input>  					<input type="checkbox" id="intelligencecheckno" onchange="intelligencecheckbox()">no</input></td>  				<td><input type="text" id="checkboxintelligenceresponse" size="60px" disabled></input></td>  			</tr>  		</tbody>  	</table>
